2's comp binary Exponent/Mantissa
How do I handle a 64 bit word where the exponent is at the beginning of the Binary?
I have 4 - 16 bit words that comprise a GPS Time stamp.
The format is as follows
Binary Format: SEEEEEEEEmmmmmmm....m
S: sign
E: 8 bit exponent
m: 55 bit mantissa
Exponent signal type:
Excess 128
MSB 2^7
LSB 2^0
Resolution 1
Mantissa signal type:
Unsigned
MSB 2^-2
LSB 2^-56
Resolution 1.3878E-17
Any ideas out there?

No, DBL has 11 bits in the exponent, not just 8. (SGL has an 8 bit exponent, but is only 32 bits long).

It should not be too hard to implement this conversion using some masking, shifting and bit twiddling. Unfortunately, you loose 3 bits worth of resolution in the mantissa going to DBL, so you would need to go to EXT.

Hello Labviewers,
So I just hooked up a couple of Honeywell UDA2182 controllers to my computer using an ethernet connection. I've established communications using modbus (specifically the Datalogging and Supervisory Control module's Modbus I/O server option) and I can tell that readings are coming through to the computer.
My problem is that it's all in some weird alien langauge. I can't tell which parameters I'm viewing data for, and the data that my computer is recieving are crazy huge numbers that don't relate to anything. My guess is that I'm supposed to somehow convert these numbers but I'm not sure how to go about it.
Thanks for any and all help/advice,
Mike
Solved!
Go to Solution.Hi Everyone!
Thanks so much for the help thus far. When I first hooked up the PLC I was indeed hoping for and expecting simple, easy to understand human readable numbers like 7.07 or 13.72. After reading through everyone's replies this morning, I have spent the better part of the day reading up on Modbus and going back through the manual that came with the PLC. Things are starting to make sense a little more but I still need any help you might offer.
I've figured out that I want to read registers (decimal addresses) 30001, 30003, 30005, and 30007. I should be able to communicate with these registers via Modbus function code 04, although, it is unclear as to whether I need to specify this function code seeing as how I'm using a Modbus I/O server in continuous operation (rather than sending one request and receiving one response at a time). These 4 registers are all classifies as type = float and I see in my manual that is says "floating point values require two consecutive registers". I am now assuming that to accurately read the data associated with register 30001, I will need to read and convert data from 30001 and 30002.
Further, it appears to me that Labview wishes to represent these register addresses with an extra 0, making 30001 -> 300001? Earlier this morning, using the DSC module's Modbus I/O server I was able to monitor register 300001 in the Distributed System Manager. The values reported to me were as follows (can choose any representation): 16,609(decimal); 1.6609000e+04(scientific); 40E1(hex); 40340(octal); and 100000011100001(binary). I was expecting a value of 7.07 (pH units) but as this is only the single register 300001 perhaps these values are only half of the human readable answer.
According to my controller's manual the default setting for communications is Word Swap = yes, or Big Endian, byte order 4,3,2,1. However, this can be changed on the controller should I need to set this parameter to Little Endian. There is also a section in the manual regarding IEEE 32-bit floating point stuff where a formula is given for calculating the floating point number from a 23 bit signed binary with 8 bit biased binary exponent. I will admit that this formula makes no sense but I'm willing to give it a shot if needs be. The crazy terminology here (mantissa, Endian, etc.) has really been difficult to assimilate.
My goal now is to try and read registers 300001 and 300002 and somehow combine the two values to produce a final human readable number? Does it seem like I'm on the right track? Does anyone have any advice as to how to combine these two register values? Thanks again. I'll report back soon.

Do numerical indicators display extended precision floats correctly?
I'm using windows XP sp2 on a new computer with a new intel processor, nothing weird. I'm displaying an extended precision floating point number using a numeric indicator that is set to display an extended data type with thirty digits of precision. I expect to see at least 19 or 20 significant digits out of my extended precision float, but the numeric indicator only ever displays 17 significant digits before going to a trail of zeros. Does the display routine that converts the float to a display string use double precision or what?
global variables make robots angryYes, I understand what you are saying and you are completely correct. The problem I have is not that I expect a mathematically perfect representation of a number, but rather that LabVIEW calculates and produces an 80-bit extended precision number on my computer and then appears to convert it to a 64-bit representation of that number before displaying it!
If you convert the extended precision value into an unflattened string in order to attempt to access the binary representation of the data, you’ll find that it is represented by 80-bits. This is a 64-bit fraction plus a 15-bit exponent plus one bit for the sign. Delightfully, the flatten to string function appears to scramble the bits into “noncontiguous” pieces, so about all I can tell for certain is that we have, as expected, an 80-bit extended precision number in memory. The documentation for the other number-to-Boolean array and bit manipulation functions I looked at (even the exponent-mantissa function) all claim to only be able to handle a maximum input of a 64-bit number (double precision float max) -correct me if I’m wrong on this one, because I’d really like to be able to see the contiguous binary representation of 80-bit extended floats.
It turns out though that what you said about not being able to tell whether we have twenty digits of precision without bit fiddling is not true at all. If you look at the program I wrote, you can prove with simple addition and subtraction that beyond the shadow of a doubt the extended numbers are being stored and calculated with twenty digits of precision on my computer yet being displayed with less precision.
As you can plainly see in the previous example I sent:
A = 0.1111111111
B = 0.00000000001111111111
A+B=C= 0.11111111111111111111
We know that
C-A=B
The actual answer we get is
C-A=0.00000000001111111110887672
Instead of the unattainable ideal of
C-A=0.00000000001111111111
The first nineteen digits of the calculated answer are exactly correct. The remainder of the actual answer is equal to 88.7672% of the remainder of the perfect answer, so we effectively have 19.887672 digits of accuracy.
That all sounds well and good until you realize that no individual number displayed on the front panel seems to be displayed with more than 16-17 significant digits of accuracy.
As you see below, the number displayed for the value of A+B was definitely not as close to being the right answer as the number LabVIEW stores internally in memory.
A+B=0.11111111111111111111 (the mathematically ideal result)
A+B=0.111111111111111105 (what LabVIEW displays as its result)
We know darned well that if the final answer of A+B-A was accurate to twenty digits, then the intermediate step of A-B did not have a huge error in the seventeenth or eighteenth digit! The value being displayed by LabVIEW is not close to being the value in the LabVIEW variable because if it were then the result of the subtract operation would be drastically different!
0.11111111111111110500 (this is what LabVIEW shows as A+B)
0.11111111110000000000 (this is what we entered and what LabVIEW shows for A)
0.00000000001111110500 (this is the best we can expect for A+B-A)
0.00000000001111111110887672 this is what LabVIEW manages to calculate.
The final number LabVIEW calculates magically has extra accuracy conjured back into it somehow! It’s more than 1000 times more accurate than a perfect calculation using the corrupted value of A+B that the display shows us – the three extra digits give us three orders of magnitude better resolution than should be possible unless LabVIEW is displaying a less accurate version of A+B than is actually being used!
This would be like making a huge mistake at the beginning of a math problem, and then making a huge mistake at the end and having them cancel each other out. Except imagine getting that lucky on every answer on every question. No matter what numbers I plug into my LabVIEW program, the intermediate step of A+B has only about 16-17 digits of accuracy, but miraculously the final step of A+B-A will have 19-20 digits of accuracy. The final box at the bottom of the program shows why.
If you convert the numbers to double and use doubles to calculate the final answer, you only get 16-17 digits of accuracy. That’s no surprise because 16 digits of accuracy is about as good as you’re gonna do with a 64-bit floating point representation. So it’s no wonder all the extended numbers I display appear to only have the same accuracy as a 64-bit representation because the display routine is using double precision numbers, not extended precision.
This is not cool at all. The indicator is labeled as being able to accept an extended precision number and it allows the user to crank out a ridiculous number of significant digits. There is no little red dot on the input wire telling me, ‘hey, I’m converting to a less accurate representation here, ok!’ Instead, the icon shows me ‘EXT’ for ‘Hey, I’m set to extended precision!’
The irony is that the documentation for the addition function indicates that it converts input to double. It obviously can handle extended.
I’ve included a modified version of the vi for you to tinker with. Enter some different numbers on the front panel and see what I mean.
Regardless of all this jazz, if someone knows the real scoop on the original question, please end our suffering: Can LabVIEW display extended floating point numbers properly, or is it converting to double precision somewhere before numerals get written to the front panel indicator?

Integer and fractional part of the number
Hello everybody,
I want to divide the floating point number to 2 integer words, first will receive the interger part of number, and the second will receive the fractional part of the number.
For example: I have number 751.98 in DBL, then I create two integer fields: first has value 751, second has value 98.
I have tried simple conversion from DBL to I16, but it always rounded me to higher interger. I don't want to round it. And I just don't know how to transform the fractional part to integer. Are there any specialized functions for this? Maybe should I use log10 or similar?
TIA,
Jacek.The place to start with this problem is the IEEE-754 numerical
representations:
32 bit floating point is internally:
highest order bit is the sign bit.
the next 8 bits are the exponent bits
the last 23 bits are the mantissa bits
the mantissas and exponents are binary.
the mantissa value in a 1.22 fixed point binary number, i.e. the most
significant binary bit is equal to 1, the next most is equal to 1/2,
the next most is equal to 1/4, etc., etc.
The exponent part can go between 2^-127 and 2^128
You should be able to cast your 32 bit float to a 32 bit unsigned
integer, separate it into sign, mantissa and exponent parts, use the
exponent to rotate left or right your mantissa decimal point by the
exponent value and then separate the whole part from the fractional
part and then put each into the I16's or U16's as you want.

Hello all,
I'm currently looking into possibilities of combining COBOL and C code in a project.
Services are written in COBOL and buffer type in use is FML32 which is converted to/from VIEW32 by means of FVFTOS32/FVSTOF32 calls from COBOL code. This works fairly well.
However, I'm currently looking into using a C "hook" that the COBOL code would call in order to deal with a few things that are difficult to do from COBOL (checking or adding specific things in the FML32 buffer that may not fit in the view). While I'm working with the FML buffer, I thought it might be a good idea to actually do the buffer conversion from the C code. But it seems to me that FVSTOF32 and Fvstof32() differs somewhat.
If I supply the FML buffer and the cobol view record to my C function and call Fvstof32(), all dec_t fields seem to turn into 0.0. Strings seem to work OK, though.
Is this to be expected? Are there fundamental differences between FVSTOF32 and Fvstof32(), or is it the COBOL record / C structure that are different, especially with regards to the dec_t type?
Any input on this welcome,
/Per
Per Lindstrom R2Meton AB, SWEDENThe advantage of using decimal is that addition, subtraction, and
multiplcation by an integer using decimal fractions produces exact results
and is not subject to slight rounding errors that can sometimes occur when
using doubles.
Another advantage is that the Tuxedo decimal data type can represent larger
integers exactly than the double or long datatypes can.
The Tuxedo decimal data type allows up to 16 base-100 digits in the
mantissa, which is equivalent to 32 base-10 digits for even exponents of 10
or 31 base-10 digits for odd exponents of 10. Integers up to
99,999,999,999,999,999,999,999,999,999,999 can be represented exactly in the
decimal data type.
An IEEE double has a 1 bit sign, 11 bit binary exponent, and 52 binary
mantissa bits. Since we are using base 2, the hardware can assume the first
mantissa bit is 1, giving an effective mantissa of 53 bits. Therefore, an
IEEE double can represent integers up to
9,007,199,254,740,991 before losing precision.
A 32-bit signed long can represent integers up to
2,147,483,647.
A 64-bit signed long can represent integers up to
9,223,372,036,854,775,807. Tuxedo transmits 64-bit longs between
heterogeneous machine architectures as 32-bit longs, so 64-bit longs greater
than 2^31-1 are suitable for transmission between 64-bit machines only if
the machines are of the same architecture and XDR encoding is not needed.
It is usually possible to code an application such that the effects of small
arithmetic errors caused by expressing decimal fractions in binary are
avoided. For example, use a printf format of "%.2f" instead of "%f" in
order to avoid embarrassing output such as "Account balance is
$342.629999999999." Another way to avoid arithmetic roundoff errors if
dealing with dollars and cents is to transmit the number of cents rather
than dollars and cents, in which case there are no decimal fractions that
cannot be exactly converted to binary. As long as the amount of money being
dealt with does not exceed 90 trillion dollars or euros, precision will not
be lost.
The preferences of the end customer must also be considered, and some
banking customers may insist on the use of decimals despite all the
explanations you can provide about how the carefully programmed use of
doubles is exact.
In general, it is possible to use doubles for most applications and still
produce exact results, and it is easier to code "c = a + b" than "decadd(&a,
&b, &c)", but there are some specialized situations for which the use of
decimals is appropriate.

Ed,
thanks for your prompt reply.
I take it that FVFTOS32 actually does other things than Fvftos32() does.
Anyway, I guess I just have to stick to using FVFTOS32 when having to dealwith dec_t data.
>
I guess this leads to the next question: What's the big advantage of usingdec_t, given the fact that there's no IBM mainframe anywhere near here? Or
would I be better off using double instead? Would double be more
"interoperable"?

Float - double == loss of accuracy? why?
The following test fails:
public void testFloat() {
float number = 46702.45F;
Float numberAsFloat = new Float(number);
double numberAsDouble = numberAsFloat.doubleValue();
System.out.println(numberAsDouble);
assertTrue(46702.45 == numberAsDouble);
}I probably just don't understand floating point data types or something, but I was very surprised that this test fails. If someone could enlighten me on WHY this fails, I would really appreciate it. For what it's worth, the value printed out for numberAsDouble was 46702.44921875 which I find entirely unexpected considering I am going from a lower precision data type (float) to a higher precision data type (double).Remember: the floating point representations (float and double) store binary values. Not decimal. The decimal values are parsed by the compiler and turned into floats and doubles in binary.
The said binary values are approximations to the decimal values. Sometimes the binary and the decimal values coincide, but some times they don't.
Floats have less precision than doubles.
The binary string that represents that number, in a float, will be interpreted differently in a double, because the double has those additional bits of precision.
Consider this code:
double nd = 46702.45d;
float nf = 46702.45F;
long ndl = Double.doubleToLongBits(nd);
long nfl = Float.floatToIntBits(nf);
long nfl2 = Double.doubleToLongBits(nf);
System.out.println(Long.toBinaryString(ndl));
System.out.println(Long.toBinaryString(nfl));
System.out.println(Long.toBinaryString(nfl2));It prints this:

Compare it to the 0's in the version that was created as a float and used as a double. -

I am querying a view in sqlserver 2000 via an odbc database link.
When I query a 26 character wide column in the view in sql developer, it will only return up to 13 characters of the data.
When I query the exact same view in the exact same sql server database from the extact same oracle database using the exact same odbc database link using sql navigator, I get the full 26 characters worth of data.
It also works just fine from the sql command line tool from 10g express.
Apparently, sql developer is confused about how to handle multi-byte data. If you ask it the length of the data in the column, it will tell you 26, but it will only show you 13.
I have found a VERY PAINFUL work around, to do a cast(column_name as varchar2(26) when I query it. But I've got hundreds of views and queries...In all other respects, the settings I have appear to be working correctly.
I can enter multi-byte characters into the sql worksheet to create a package, save it, and re-open the package with the multi-byte characters still visible.
I'm using a fallback directory for my jdk with the correct font installed, so I can see and edit multi-byte data in the data grids.
In this case, I noticed the problem on a column that only contains the standard ascii letters and digits.
Environment->Encoding = UTF-16
All the fonts are set to a font that properly displays western and ge'ez characters. The font has been in use for years, and is working correctly in all other circumstances.
The Database->NLS Parameters tab under sql developer preferences shows:
language: American
territory : American
sort: binary
comp: binary
length: char (I've also tried byte)
If there are other settings that you think might be relevant, please let me know.
I've done some more testing. I created an oracle table with a single column and did an insert into ... select from statement across the database link. The correct, full-length data appeared in the oracle table.
So, it's not a matter of whether the data is being returned or not, it is. It is simply not being displayed correctly. It appears that sql developer is making some unwarranted decisions about the datatable across the database link when it decides to display the data, because sql plus and sql navigator have no such issues.
This is really a very serious problem, because if I cannot trust the data the tool shows me, I cannot trust the tool.
It is also an invitation to make an error based upon the erroneous data display. -

Conversion of Packed Decimal Numbers to Java Data Types
Hi all,
I'm working with a mainframe file which contains datas in Packed Decimal Numbers.My requirement is to convert these datas to Java datatypes and also to convert the Java datatypes to Packed Decimal Numbers before storing them in the mainframe.
Can anyone help me out with any code for converting Java data types to/from other data formats such as: EBCDIC, IBM370 COMP (binary numbers up to 9 digits), and COMP-16 (packed decimal numbers)?
I would hugely appreciate any response to my query.
Thanking you all,
Kaushik.Rather than go that route, I'd instead look into providing a "service" on your mainframe to:
1) provide a textual representation of the numbers (from native to text)
2) read text, converting to native numeric storage
And use that service to retrieve that information by your Java app (1)Similarly, instead of trying to write natively-formatted numbers from your Java app, I'd write it as text and make that same "service" read the text (2)
This is the kind of thing XML is for. -
Sqldeveloper ORA-12705 NLS parameter problem

I configured sqldevloper with Language=American, Territory=Ecuador, Sort=Spanish, Comp=Binary and Date Language=American. However, I get connected to the db succesfully, but I got an annoying message (2 times):
An error was encountered performing the following operation:

It could be great if someone could help me to get rid of this messages...

I realized that the error goes away if:
a) I remove ORACLE_HOME from the environment, i.e. "set ORACLE_HOME=" in the does box or
b) I set ORACLE_HOME=C:\programs\oracle\product\11.1, where this is an 11.1 SERVER ORACLE_HOME
Using regmon I saw that sqldeveloper does not access the Windows registry. Unfortunately I was unable to determine the root cause why the error occured when ORACLE_HOME pointed to the 10.2 client ORACLE_HOME. All I can say is it was not due to file access permissions.
I was also unable to determine why sqldeveloper kept using C:\programs\oracle\product\10.2\jdbc\lib\ojdbc14.jar even when ORACLE_HOME did not point to C:\programs\oracle\product\10.2.
With ORACLE_HOME=C:\programs\oracle\product\11.1 the following jar file was used for JDBC:
C:\programs\oracle\product\11.1\jdbc\lib\ojdbc5.jar
When I'm setting "set ORACLE_HOME=C:\programs\sqldeveloper", which is the installation directory of sqldeveloper, then it works fine and filemon utility shows that it uses this JDBC jar file:
C:\programs\sqldeveloper\jdbc\lib\ojdbc5.jar
Unfortunately neither Oracle® Database SQL Developer Installation Guide Release 1.5 E12153-02 nor Oracle® Database
SQL Developer User’s Guide Release 1.5 E12152-05 (the latest editions as of Dec 08) say anything about ORACLE_HOME that applies.
However this info in the "User's Guide" is noteworthy: "_Note that SQL Developer does not use default values from the current system for globalization support parameters_;"
This seems to indicate that any NLS_* parameters in the registry and environment (DOS box) are ignored. Go to Tools > Preferences > Database > NLS in sqldeveloper to set them. But there is no way to set the character set! -
How to read labview binary files in Matlab
I would like to read Labview binary files with Matlab. I read some articles of the subject and I am more interesting in know how labview store this data into file. What is the format use by Labview to store this data?
Any help is appreciated,
HernandoThe term "binary file" means that the data on disk is a (pretty close) duplication of the binary format of the data in memory. For example, a String will appear as an array of Bytes that, if looked at with a text editor, would be "human-readable".
An I32 or U32 integer would take 4 bytes, but the order (or "Endian setting") can be Big-Endian or Little -Endian (and I won't confuse both of us by trying to say which is which). Thus the number "1" would appear as four byte of 0, 0, 0, 1 or 1, 0, 0, 0. Floating point (Dbl) also has an "Endian" consideration, but the numbers are encoded as a mantissa and exponent, with sign appearing somewhere. However, if you get the Endian and precision (Sgl, Dbl, etc.) right, both MatLab and LabVIEW should be able to read each other's data.
Be careful with Booleans. It wouldn't hurt to do an experiment and see how many bits/bytes are used for simple Boolean data.
One other "gotcha" -- in LabVIEW, you can prepend Array and String writes with a U32 that is the length of the Array/String -- you obviously want to take this into account.
Something that I've found helpful when dealing (in both Matlab and LabVIEW) with "unknown" binary data files is to use an old-fashioned "binary editor", something capable of displaying a file as Text and Bytes. Strings "stand out", and if they seem to be preceded with 4 bytes that are mostly 0 with one Byte more-or-less the length of the String (sign that String Length was prepended). If you see a lot of byte data that look like they could be 2 or 4 byte integers, they probably are. If they are four bytes of numeric data that have few zero bytes (i.e. if most of the 32 bits seem to be used), they may well be floats. Make a guess at the format and write a short routine to read according to your guess -- do you get meaningful data? Go ahead, be a Scientist, not an Engineer -- study the data, form a hypothesis, then design and do an Experiment and see if you need to reject your hypothesis ...
Bob (Neuroscientist) Schor -
Im a new logic and mac user. I love the experience so far except when it comes to Logic. When swipe comping Logic inevitably crashes at random points. I cant seem to find a pattern. It happens when theres audio playing and when its still, with multiple takes and with just one. Im on a Mac Book Pro 15" with 2GB of ram and pleanty of HD and I use a PODxt Live for my input and monitoring device. I have the latest drivers from Line 6 for the Pod and this had been stable in all other recording and audio packages, including garage band, so I'm sure its not that. Has anyone else had this problem? I really dont want to return this software as I really do like it otherwise.
Heres my crash dump:

Create a new empty project (compose for instance). Add a stereo real instrument channel with record on. Block off 4 bars and set them up to loop. Hit 'R'. Wait for 4 loops. Hit Space. Wait a couple seconds. Hit 'R'. Boom it hangs every time. -
Add a unique constraint on binary XML table
How add a unique constraint of "brevet" field?
The following INSERT failed
SQL Error: ORA-19025: EXTRACTVALUE renvoie la valeur d'un seul noeud
19025. 00000 - "EXTRACTVALUE returns value of only one node"
If the ALTER is made after the INSERT is done, INSERT is valid but ALTER failed with the same error message!

but this is probably unadvisable.
I suggest an alternative is for you to look at XMLINDEX so that you can bring the 'proper' XML functions into play like XMLTABLE etc. -

...Looking at your binary search method:
public static int binarySearch( Comparable [ ] a, Comparable x)I see it expects to be fed Comparable objects. So, whatever you're feeding it, it's not a Comparable (ie: it doesn't implement Comparable), hence the CCE.It's even worse: if an A is a B it doesn't make an A[] a B[].
kind regards,
JosMy post didn't make much sense: if there were no Comparables provided as an argument, it would have thrown a compile time error. The problem lies in the compareTo(...) method. -
Convert Raw Binary String to InputStream
Hi i want to upload a {color:#003366}JPG image file{color} in a {color:#003366}BLOB{color} field in database. At first i was using {color:#003366}AJA{color}X to send file {color:#003366}path{color} to the {color:#003366}servlet{color} creating a {color:#003366}file Object{color} from it, then {color:#003366}FileInputStream{color} from it, and finally passing it to {color:#003366}preparedstatement.setBinaryStream({color}) method. It worked great. But since{color:#003366} Firefox 3{color} stopped sending full path to database i have to use another method.
So instead of sending image path i used {color:#ff0000}nsIDOMFile{color} property of Firefox 3. It has a method {color:#003366}getAsBinary(){color} which Returns a DOMString containing the file's data in {color:#003366}raw binary{color} format. Now i access this {color:#003366}string{color} from servlet using{color:#003366} request.getParameter(){color} method which creates a {color:#003366}String containing bit code of the image file{color} (I suppose). Now how to convert this string to {color:#003366}InputStream{color} so that i can store this in BLOB field in database using prepared statement.
Right now I am using following code but it doesn't seem to work.
String image=request.getParameter("image");
try{
InitialContext context = new InitialContext();
dsource = (DataSource)context.lookup("java:comp/env/jdbc/DataSource");
con = dsource.getConnection();
ps = con.prepareStatement("SOME STATEMENT");
ByteArrayInputStream imagestream = new ByteArrayInputStream(image.getBytes());
ps.setBinaryStream(1, imagestream, imagestream.available());
int i = ps.executeUpdate();Edited by: Wonder01 on Oct 22, 2008 12:24 PMYeah i came across that too. But these show either iframes hack method (which really isn't ajax) or else writing large pieces of code just to generate the binary stream of the file, then manually creating multipart/form-data request were the only options until Firefox 3 introduced nsIDOMFile. See this and read first few lines (you'll understand what i mean). So i send request in the form of a parameter containing Raw Binary format of the file
Now going over to the servlet side i need to somehow accept this parameter and insert in database. First i need to know how should i receive this on servlet (By using request.getParameter() or some other method). And secondly, how to convert that to either a byte array or InputStream. I searched for it and think this might be useful. This page shows 1.) how to convert an array of raw binary data into an array of ASCII 0 and 1 characters and 2.) how to convert a String to byte array where each char of the String represents an ASCII '0' or '1'. But what i nedd is slightly different, I need to convert a String containing Raw Binary into byte array.
And thanks for the information on the file paths. It was really helpful
