Converting Hex to Decimal

hi,
I want to convert my hex value to decimal. How can I do this? help me pls.
Suku

actually...the hardware I'm interacting through com port will retrun data every time in different length. I'm reading that data, byte by byte only. So in that second byte I'm getting the length of the data returned by the hardware. Now for executing my loop that length is required.
while ((ch = (byte)portInStream.read())!=-1)
indata[i] = ch;
String hexString = Integer.toHexString(indata);
hexDec = Integer.parseInt(hexString);
strData =strData + hexString;
i++;
if(i==15) break;
in the above code I'm reading 15 bytes from the port. But it may vary...to know the length I want to convert the second byte to int.

Convert hex to Decimal and keep leading zeros..

Hi,
I hope you can help?
How to convert hex to Decimal and keep leading zeros
I read 002C, hex, and I want to convert it to 0044 decimal.
sscanf (MyNum, "%4x", &DecNum); will only give me 44.
It have been working up till I started to get leading zeros.
We will always have a 4 digit hex input in a range
We must have the leading 00 in this case.
How is this best done?
Thanks for the help

Hi,
I don't really understand your problem. Is this stuff what you need ?
int main (int argc, char *argv[])
const char MyNum[] = "002C";
int DecNum;
sscanf (MyNum, "%4x", &DecNum);
printf ("%04d", DecNum);
getchar ();
return 0;
"0044" appears on standard output when printf function executes...

Formula to convert Hex to Decimal

Hello All,
I have "upgraded" from AppleWorks to iWork Numbers. Yes I've read all about how somethings didn't get ported over, etc. What I need is a formula to convert base 16 to base 10. Any ideas how to do this? I see that numbers has a formula editor so is it possible to make up a conversion formula? Someone done this who would like to share?
Thanks,
Dan

Dan,
Here's a brute-force solution. There may be more elegant ones out there.
DEC formula is: =IF(ISERROR(LOOKUP(MID(A2, 1, 1), LOOKUP TBL :: A$1:A$16, LOOKUP TBL :: B$1:B$16) * 16^3+LOOKUP(MID(A2, 2, 1), LOOKUP TBL :: A$1:A$16, LOOKUP TBL :: B$1:B$16) * 16^2+LOOKUP(MID(A2, 3, 1), LOOKUP TBL :: A$1:A$16, LOOKUP TBL :: B$1:B$16) * 16+LOOKUP(MID(A2, 4, 1), LOOKUP TBL :: A$1:A$16, LOOKUP TBL :: B$1:B$16)),"", LOOKUP(MID(A2, 1, 1), LOOKUP TBL :: A$1:A$16, LOOKUP TBL :: B$1:B$16) * 16^3+LOOKUP(MID(A2, 2, 1), LOOKUP TBL :: A$1:A$16, LOOKUP TBL :: B$1:B$16) * 16^2+LOOKUP(MID(A2, 3, 1), LOOKUP TBL :: A$1:A$16, LOOKUP TBL :: B$1:B$16) * 16+LOOKUP(MID(A2, 4, 1), LOOKUP TBL :: A$1:A$16, LOOKUP TBL :: B$1:B$16))
Be sure to Format Col A of both tables to Text.

Java code to convert - Hex to Dec

I'ld like to convert an Integer or a String from hexadecimal format to a decimal format;
For example: 30 give 0; 50 give P and so on.
Can any one help me sending to me a java code that do it please?
Thanx a lot

This doesn't convert hex to decimal, but it does convert hex to the character representation, which is what it sounds like you want. At any rate, given "30" it will print "0" and given "50" it will print "P". Also, given "P" it will print "is invalid".
        try
            int in = Integer.parseInt(s, 16);
            Character ch = new Character((char)in); // should validate range here
            System.out.println("In: " + s + ", out: " + ch);
        catch (NumberFormatException e)
            System.out.println("In: " + s + " is invalid.");
        }

You can use the typecast function to do this.

Checking and Converting binary, octal, decimal, and hex

Hi,
I have a classroom project which will need to validate that data entered in a text is of a certain type with a keyListener, and then convert that value to the other 3 types.
I know character.isDigit will handle the decimal case, and that I can then use Integer.otString methods to convert to binary, octal, and hex, but what about the other cases?
Thanks

OK, this isn't working. If I've already established
that the string entered into, for example, the
integer-only textfield is a valid integer, I should be
able to simply use integer.parseint(s, 2) to convert
it into binary, right?Not exactly. You should be able to use Integer.parseInt(s, 2) to return the result of converting it from binary representation. You appear to think that this affects whatever "s" refers to, which is not the case. Note also, that method returns an int which is the decimal value in question.
When you are thinking of int variables, be careful not to think of them as "decimal" or "binary". They are neither. They are just numbers. "Decimal" and "binary" are text representations of numbers, so those concepts can only be applied to strings.
Integer.parseInt(s, 2);
txtBin.setText(s);So here you want to assume that the input is a string that represents a number in decimal, and you want to find the string that represents the number in binary. Like this:// convert string in decimal representation to number
int dec = Integer.parseInt(s);
// convert int to binary representation as string:
String binary = Integer.toBinaryString(dec);
// write that to the text field
txtBin.setText(binary);You could use a one-liner to do that, but you'll need the "dec" variable to set the other text boxes.
Rembering why I hate OO...All of what I said there is true in just about all computer languages, OO or otherwise.

Converting character to decimal format

hi
i am working on a development where the selection screen has date and time as select options.
and based on the input i have to concatenate date and time into the format- DD.MM.YYY HH.MM.SS
there is a value in the table that has a field containing the above value and i have to fetch the data based on this input.
Now the problem is the field in the table is of format DECIMAL of 16 length.
i want to know how can i pass this value to the select statement.
thanks in advance

How to convert string to decimal in data association function?

In a BPM Script component, how in the Data Association can I use an expression to convert an argument from String to Decimal? I have a Process argument named percentage which is a string. I need to set the value of a data object called signed to either "Y" or "N" based on the percentage being greater than 0.4. Something like this:
(percentage > 0.4) ? "Y" : "N"
The problem here is that percentage is a string, so must be converted to a decimal value before the compare will work. I cannot find a function that allows that. I need something like parseDecimal(percentage), but the Expression Builder does not offer that for a string using a Simple Expression.
If it cannot be converted, is there another way to do this?

Guessing you figured this out on your own, but if you wanted to use a Script activity one way to do what you want is when you're creating your data associations drag the "Expression" icon in the middle and double click the icon in the middle you just added:
Get out of the Simple expression mode and into the XPath expression mode by clicking the dropdown in the upper left corner -> click "XPath Exp".
In the Functions dropdown on the right, click "Conversion Functions" -> click "number" and then insert it into the expression.
In the Variables list, select your string variable and insert it into the number function so that it looks something like this: number(bpmn:getDataObject('myStringVariable'))
Click OK
Click your expression icon in the middle and drag it over your decimal variable.
To have it evaluate and return a Boolean expression in your Script activity, add a Boolean process variable and add an XPath expression as described above except have the logic be this: number(bpmn:getDataObject('myStringVariable')) > .4 (the "greater than" shown above is added to the expression by clicking "Logical Functions" from the functions dropdown). Click OK and drag your expression icon over your Boolean variable.

Converting hex to dec

Hi everybody,
I want to join this two numbers and convert them from hex to dec. I have tried using joint and conversion but I still couldn't work it. In the following screen shot I took it suppose to be 3E8 in hex which equals to 1000 in dec. I need suggestion from you how to approach this.
Thanks

As I was reading all the answers about converting Hex to Dec,I found out that many of you are making it so complicated.To make it easier for a learner or beginner,this is what it takes:
Open a blank VI
Click on numeric control
Right click on the same numeric control
Scroll down to "Representation"
Click on "U8"
Go to numeric indicator and repeat step 4 and 5
Then right click again on numeric control
Scroll down to "Properties" and click
Click on "Data entry",if necessary,change the minimum and maximum
Pass to "Display format"
Click on "Hexadecimal" then you are done.The rest is to go on the block diagram to wire the numeric control to the numeric indicator and it works.
You can do the same process reverse for dec to hex.But you must know that what we did for "numeric control" on (Hex to Dec) will be done to "numeric indicator" on (Dec to Hex).This same process can apply to octal and binary without the use of complicated array,string while loop and so on...
I'm a beginner in Labview and I understand that you need to explain more to understand better.
If you really read all of the comments, you would see that Altenbach already stated this (saying it is just a cosmetic property for the indicator).

Converting Hex to Integer Value

I'm trying to convert hex code to the corresponding integer, which can then be used to display a character.
For example I have the code.
int i = 0xE7;
System.out.println(i);
System.out.write(i)This produces the output as expected with the first output outputting 231, and the second line outputting the corresponding character.
My problem comes when trying to make it so the hex code is variable.
For example, I receive an output of 7
This output is then the last digit of the hex code (so i check if needs to be converted to a, b etc.) then try and combine it with the prefix 0xE to create the hex code.
I'm not quite sure how to do this bit as I cant carry out
num = 7;
hex = "0xE"+num;
int i = hex;as the last line doesn't calculate due to hex being a string.
Many thanks for your help.

The char array is currently being created using:

Look this is OK, you need to do nothing but just the following:
// I am using the very first example you provided
// i is the index for the char
String hex = "0E" + hexchar;
Integer.parseInt(hex, 16);
System.out.println(i);

Convert Mainframe Packed Decimal to Oralce Number Format

Dear all,
I am having a file in which amount fields are given in a Packed Decimal format. Can anyone suggest me how I can read this data element from the file and convert it into Oracle Number datatype.
File is a fixed length. All the amount fields are given in Packed Decimal Format and rest of the fields are given in text format.
Thanks and regards

Hi,
Firstly thanks for your reply.
Actually I am not using SQL Loader to load data from
a flat file to Oracle table. I am writing a custom
program that reads the file and populates the oracle
table. I'll put aside the question of 'why' you'd want to do that. SQL*Loader's singular purpose in life is to load flat files of data into Oracle DB. Sometimes there is a reason for reinventing the wheel.
How does your program communicate with the Oracle DB? If utilizing ESQL and Pro*Cobol (or Pro*<whatever> ) you will have read the data into a variable of some type in you host language. The variable of the host variable to hold the value (if you did a 'select from' that table) would be the correct target type for an insert statement. Whatever host language type conversion is available bewteen those two types ( if they are different at all ) is all that is needed. The precompilers have converters between certain native host and internal Oracle types built-in. It is how you get any data between the two systems. This is only a problem if the host language has no converter between the numeric types (if differnet.). When you read from the flat file are you reading it into a native packed decimal in the host language?
ODBC/JDBC similar strategy..... cast conversion between the native type that Oracle wants and the one into which your custom program reads it into.
So I want to know whether there are any Oracle
utility programs that will convert the packed decimal
to a oracle number format or not.There are Oracle routines that convert into the native Oracle DB formats. There are implicitly available through the normally utilized interfaces to OCI ( ESQL and ODBC/JDBC ) . There are none decoupled from those interfaces though (that I know of).
There are no standalone programs that mutate a flat file into another flat file that then could be loaded. That's is typically slower and utilzes more space than most customers want than just directly inputing the data into Oracle DB.

Property to set hex/binary/decimal format at run time?

Hi, I'd like to allow my user to choose between hex/binary/decimal formats in his number input. I'm happy to do the radio button stuff and the code to "hear" what he wants, but I can't find a property of my variable which selects the format at run-time - there is of course the "Format & Precision..." which I can get at by right mouse click BEFORE running, so I know it's likely to be available at run-time. Any suggestions welcome. Thanks, Richard.

It's not necessary to use property node because you can use the builtin
property of the indicator.
Click the rigth mouse button over the indicator and select show radix.
On the left side of the indicator appear radix that you can push to choose
between hex, binary, octal and decimal.
Bye
