Converting HEX to FLTP

Hi All,
I want to convert a hex value to FLTP. How can I do it?..
Normal covnersion rules say it is first converted to a packed number and then to floating point number giving me the wrong results.

Hi
As you have said that ABAP supports automatic type conversion for all the fields with the exception that you can't assign type t to type d and vice versa.
I feel whatever you are getting is the correct value after automatic type coversion.
Try to use correct data types wherever possible.SAP is also recommending this.

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.");
        }

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.

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);

Hello everyone..
I am currently working on a project in which I have to read the data from a unit and display that data using LabVIEW. I am using serial communication for reading the data. The read data is in hex format.
Now, I want to convert this hex string to a time stamp value. I am reading total 16 bytes. How to convert this hex data to a time stamp value. I have developed a VI. But I want to know that the displayed time stamp is correct or not? Or suggest me some other solution.
I am using LabVIEW 2011.
Thanks & Regards,

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...

How to convert hex into a string value

hei evryone!
can anyone please help me on how to convert a hex value into a string suppose.. Example i want to convert 4275646479 which is a hex value, into a string "BUDDY"? how will i do that???
Any suggestion, tutorial site would be appreciated?
Thx!

something like this will convert string to byte[]
e.g.
you want to convert following.
656667 => ABC
String toConvert = "656667";
byte[] returnVal = String2byteArr (toConvert );
String FinalStr = new String(returnVal);
public static byte[] String2byteArr(String Result)
byte[] byteRet = new byte[Result.length()/2];
int k=0;
for (int j=0; j<(Result.length()); j+=2)
try
Integer I = new Integer (0);
I = I.decode ("0x"+Result.substring(j, j+2));
int i = I.intValue ();
if (i > 127)
i = i - 256;
byteRet[k++] = new Integer(i).byteValue();
catch(Exception e)
System.err.println(e);
return byteRet;
}// String2byteArr
Hope this will help you, So that i can get 3$ (:-)

Converting hex to number & date

Hi!
Im having a problem converting the hex code to the number & date.
select low_value,high_value from ALL_TAB_COL_STATISTICS;
Iv tried HEX_TO_CHAR and that works fine.
select column_name, UTL_I18N.RAW_TO_CHAR(low_value),UTL_I18N.RAW_TO_CHAR(high_value),low_value, UTL_I18N.RAW_TO_CHAR(high_value) from ALL_TAB_COL_STATISTICS where owner = 'user' and table_name = 'table_name';
if you type this statement you will see that numeric fields and date fields get caught up in (¿) type of fields.
Any solution for this?

I can get it to work if I create a view with this statement and add a specific table_name. But I need to get this to work in the whole schema/user without entering a specific table.

Could you please assist?

Problem solved, no need to look into it. Thank you

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.

HERES MY QUESTION,
1.how can i convert this hexadecimal coordinates so that when i query, a decimal value will appear instead of hex. this hex values are the lines in the map.heres the info about the hex value above. we need to parse or cut the hex into 8..
00000001
00000001
00000006 ==>number of coordinates(ranging from 1-F, this example means 6)
06D4E833 ==> X1
074B69EC ==> Y1
06D4E91F ==> X2
074CO184 ==> Y2
06D50C58 ==> X3
074C031E ==> Y3
connecting 4 coordinates/2points/ will make 1 line
connecting 6 coordinates/3points/ will make 2 lines
connecting 8 coordinates/4points/ will make 3 lines
connecting 10 coordinates/5points/ will make 4lines
connecting 12 coordinates/6points/ will make 5lines
connecting 14 coordinates/7points/ will make 6lines
and so on..
In the example above there are 6 coordinates
point(X1Y1), point(X2Y2), and point(X3Y3). Connecting all 3 points will make 2 lines). computing the total length by phytagorean therorem
LINE1 length=square root of X2-X1 squared + Y2-Y1 squared
LINE2 length=square root of X3-X2 squared + Y3-Y2 squared
total length = LINE1 + LINE2
how can i implement this so that when i query specific grarep and attr_posn, a computed total length in decimal value will appear instead of hex..thanks
