Convert hexadecimal output to decimal (number)

I am reading hexadecimal format from the output of the VISA read block and I want to convert it to the decimal preferably exponential format.
Example of what I read is 76 00 02 (in dec: 7.600 E+2).
I know there is "type cast" block that converts nicelly but I am not sure what to specify for a type input.
Can you show me how to apply this type cast block for in my VI so that it converts hex string (76 00 02) into exponential string/number (7.600 E+2)?
I attached my VI so it is more clear.
Thanks everybody,
Pedja

Looking at your code I see that you have not a hexadecimal string coming
back but instead a binary string. The fact that you display the string
as hexadecimal in the string indicator is just showing you the ASCII
codes of the string characters as hexadecimal numbers.
The funct
ion From Hexadecimal String expects a clear text string with
hexadecimal characters but that is something entirely different from a
binary string you choose to display as hexadecimal numbers.
An example: the binary string 7600 02 you receive from the device is in
fact the character 'v', a null character and a 02 character (or in ASCII
terms a start of text character).
So assuming your example is right (which I have to admit seems very
strange and therefore suspicious to me) you would have to do something
more like included example. But as I said I have little understanding
why the hexadecimal interpretation of the binary values should
correspond to the decimal value you want to have!
Also as you can see there is not really clear where the 00 character
belongs to. The two methods where it is either part of the multiplier or
the exponent both produce the same result for this particular example.
Which one is right if any, should be tested.

Output decimal number through GPIB or VISA

I was wondering if it is possible to output a decimal number, as in not a string, through the GPIB or VISA commands. I am trying to communicate with a machine that I think wants to get a number, and can't understand what I am sending when it is in a string format.
thanks

It is possible to transmit such a number over GPIB. I would double check the instrument manual for what it requires. I'm going to assume that you are using a long to represent a floating pont number. Here is some example code for how you would pass this number to the GPIB ibwrt() function.
int ud = ibdev(board,PAD,SAD,timeout,eot,eos);
long myNumber = 4.2;
ibwrt(ud, &myNumber, sizeof(long));
Essentially, the driver will break down the 32-bit number into 4 8-bit chunks.

How could I choose some bytes from HEX string and then convert it to a decimal value?

Hi I am working with an OMRON E5EN temperature controller using VISA serial to get data, I send the Read from Variable Area command and get this string in hexa 0230 3130 3030 3030 3130 3130 3030 3030 3030 3030 3041 3203 71 or .01000001010000000000A2.q in ASCII this string means:
02 STX
3031 3030 Node and subadress
3030 End Code Normal Completion
3031 3031 Command Read from Variable Area
3030 3030 respt code Normal completion
3030 3030 3030 4132 Hexadecimal A2 = 162 (this is the temperature data that I want to show in decimal)
03 ETX
71 Block Check Character
I want to choose the eight bytes for the temperature data and convert it to a decimal number. I have seen the examples to convert a Hexa string to decimal but I do not know how to choose the specifics bytes that I need.
I have look for a driver but i didn´t find any. I am a beginner so please include especific topics for me to study in your answer.
Thanks
Carlos Fuentes Silva Queretaro Mexico

If the response always has the temperature starting with byte 15 and is always 8 bytes in length, you can use the String Subset function to get those bytes out of the string. Then use Hex String to Number to convert to a decimal number.
Well someone already beat me to the solution:

How to convert fractional decimal number to hex number?

Hi,
Can any one help me to convert the fractional decimal number to its equivalent hex number and vice versa ?

This question is not clear at all.
"Fractional decimal" is not a data type, but a way of formatting in readable form using numeric characters and a decimal separator.
Same to "hex number", but only for integers.
What do you mean by "convert"? Do you want to keep the value the same or retain the bit pattern of the numeric data type?
Hexadecimal is for integers. Are you talking about fixed point?
We clearly need significantly more information. What are the input and output data types? What are you actually trying to do?
Do you have an example input and corresponding output?

Is it a float or a double?
For a float, the decimal should be 4 bytes (small numbers like 1.1 start with the byte 0x40). Convert these 4 bytes to an int, using byte-shifting would probably be easiest.
int value = ((b3 << 24) + (b2 << 16) + (b1 << 8) + b0);//b# are bytesNow to convert it to a float, use
Float.intBitsToFloat(value);Now if you want double percision, You will have 8 bytes instead of 4, and need to be converted to a long instead of an int through byte-shifting. Then use Double.longBitsToDouble(long bits) to get the double

Program to convert binary to decimal number?

I only know how to do a program that converts only 4 numbers, but it to convert any amount of digits the number enters, I think you need to use a loop or something, but I'm not sure how. Could someone please help me? This is my code so far:
import javax.swing.JOptionPane;
public class bintodec {
     public static void main (String[] args) {
          String input;
          int number,digit1,digit2,digit3,digit4,result;
          input = JOptionPane.showInputDialog ("Enter a binary number.");
          number = Integer.parseInt(input);
          digit1 = ((number % 10000) - (number % 10000 % 1000)) / 1000;
          digit2 = ((number % 1000) - (number % 1000 % 100)) / 100;
          digit3 = ((number % 100) - (number % 100 % 10)) / 10;
          digit4 = (number % 10);
          result = (digit1 * 8) + (digit2 * 4) + (digit3 * 2) + (digit4 * 1);
          System.out.println ( "Binary number: " + input + "\nConverted Decimal Number: " + result);
          System.exit( 0 );
     } // main
} // bintodecany help is super-appreciated.

Convert a String to Decimal Format in European format

Hi Experts,
I am having a string as a context type for a input field, where the user can enter the Price, I need to convert the same into European format "###.###,00", I am using this below code to convert the string to decimal format
User will enter the input as 10 as it needs to be converted into 10,00. Also, 1000 which has to be converted as 1.000,00
String Str1 = wdContext.currentvn_temptable.getVa_TempUnitPrice();
Locale mylocale = Locale.GERMAN;
String pattern="###.###,00";
NumberFormat nf = NumberFormat.getNumberInstance(mylocale);
DecimalFormat df = (DecimalFormat)nf;
df.applyPattern(pattern);
String output = df.format(Str1);
wdComponentAPI.getMessageManager().reportSuccess("Unit Price" + " " + pattern + " " + output);
When I execute the above code, i am getting an error called "Malformed Pattern ###.###,00"
Please let me know, how to convert a String to Quantity in European format
Thanks & Regards,
Palani

Hello!
Try to change your pattern to this one
Locale mylocale = Locale.GERMAN;
String pattern = "#,#00.00";
NumberFormat nf = NumberFormat.getNumberInstance(mylocale);
DecimalFormat df = (DecimalFormat)nf;
df.applyPattern(pattern);
String output = df.format(1111111.222);
Pattern has an influence on number of digits between separators, but you have to use ',' for grouping and '.' for decimal. Character values for separators correspond to your Locale object.
Thanks, Mikhail

Conversion of hexadecimal file to decimal file in labview

hi all,
I took a measurement from an anemometer by its original program. I attached the file below. I want to convert this file to the decimal file. I all know is the data in file are in hexadecimal and 16-byte. How can I convert this file to decimal one? I prepared something as I saw in this forum but it gives me just one number. I attached the vi below too.

@Bijay: as the file is no spreadsheetfile it doesn't make sense to load it using ReadFromSpreadsheetFile!
You may try this:
The file seems to contain SGL values so I typecasted them. If that's not the case you use the U8 array to do your own computations...
Edit:
Using ReadBinaryfile is somewhat easier...
"the data in file are in hexadecimal and 16-byte."
The file isn't in hexadecimal, it's just binary. And what do you mean by "16-byte"???

Convert IPv6 address to decimal

How do we convert an IPv6 address to its decimal equivalent using java?
I could find different tools on Internet but not the java code for the same.
Any help would be much appreciated.
Thanks.

Hello EJP
Please visit the following URL:
https://www.ultratools.com/tools/decimalCalcResult?ipAddress=805b%3A2d9d%3Adc28%3A0000%3A0000%3Afc57%3Ad4c8%3A1fff
This converts the IPv6 address (which is in hexadecimal format) to a decimal number.
I need to implement this functionality. I could not find any method in java.net.Inet6Address class for this.
To convert an IPv4 address which is in String format to its decimal equivalent, we can use following method:
<code>
long stringToLong(String ipAddress) {
          String[] octets = ipAddress.split("\\.");
          long intValue = 0;
          long currentOctet;
          for (int i = 0; i < octets.length; i++) {
               currentOctet = new Integer(octets[(octets.length-1)-i]).intValue();
               intValue = (currentOctet << i*8) | intValue;
          return intValue;

Converting hexadecimal XML data to a string

Hello!
Until now I generated XML data with the FM 'SDIXML_DOM_TO_XML'.
After that I did a loop over the xml_as_table in which I was casting each line of that table to a string.
ASSIGN <line> TO <line_c> CASTING.
After the inftroduction of unicode in our system I get a error:
In the current program an error occured when setting the field symbol <LINE_C> with ASSIGN or ASSIGNING (maybe in combination with the CASTING addition).
When converting the base entry of the field symbol <LINE_C> (number in base table: 32776), it was found that the target type requests a memory alignment of 2
What does it mean? Does somebody have a solution.

Comma or point in decimal number

Hi,
I wonder how to handle decimal number input from jsp page with comma or point. Is there a way to take care of this automatic so a comma get parsed to a point or vice versa.
Thanks in advance.

I don't know if it will be a comma or a dot that is inputed. My keyboard uses a comma on the numeric pad but if i change it to a US keyboard it will use dot instead so I can't tell what a user will input. And if I understand everything when java calculates a double it has to be with a dot, or am I completly wrong.
So with this in mind i decided to replace all dots with a comma and then parse it to a double with NumberFormat and do my calculation and then format it with NumberFormat again. This works fine and gives me a nice output if no one tries to input more than one point or comma.
I can't think of another way to do it so if this is completly wrong so please point me in the right direction.

Prefix zero to a decimal number

Hi All,
I need to send a value to third party system. The value is a decimal number but before sending it i need to prefix zero.
Eg: 1.25---> 00000000001.25
The Functiom module CONVERSION_EXIT_ALPHA_INPUT works only for integers.
Can you please suggest a function module which wil satisfy my requirement.
Thanks

Use a For loop to index into the array, then use the Not Equal To Zero comparison to convert it to true/false. Then Index out of the For and use the Bool Array to Int from the boolean pallete.

My graphical display of converted hexadecimal numbers changes with every run!

Dear all,
I've created a Vi that can select and convert hexadecimal numbers from a string array. These hexadecimal numbers contain acceleration data (units g).
My string array (from line 68+) places every 10 rows a 1 line of hexadecimal number with a length of 300. I've managed to convert this into 1D array DBL.
My current problem is, when I run my for loop my graphical representation of the acceleration data changes overtime!
Can anybody help me solve this problem?

I found a little dead time and decided to have a little fun cleaning up. Notice that I removed the FOR loops on the left side. The biggest thing was that I used the Read Text File configured to read lines (it gives me an array of the lines in the file), got rid of the first 68 lines, and then passed that array into the FOR loop. Your code there was next to impossible to figure out, even with the comment. I have no clue where you came up with trying to update every 25ms. It shouldn't take your processing that long. Instead, just index out the lines inside of the loop.
There's still a bunch of cleaning up to do, but it's quitting time for me. I'll try to get on sometime this weekend of you have more questions.
