• string to a rounded decimal number question

  Hello everyone, I have a lot of data that I have to draw the graphs and Im trying to automate the process. Now Im reading data in a *.txt file and when I try to convert it to a table of numbers all the disapper of digits after the decimal point. What I am doing wrong? Below is my VI

  That's your problem. As previously reported by Bill, you must use the Fract/Exp string to Number function. Please use the help of LabVIEW. He could tell you what this function.

  I understand not all of gymnastics you do with trying to read the file. Why do you use the substring to replace to remove the first 11 characters? Subset of the string would be more appropriate. Have you tried to use just read the spreadsheet file? You can change the format string to specify the location codes (see using LabVIEW).

• Convert a single number to a hexadecimal string of 32-bit and exchange the high and low bytes

  I need to convert a number single precision floating decimal to hexadecimal format of 32 bits, share the high and low bytes and that convert a hexadecimal string.  I tried to use the 'Word of Swap' function but it seems to have no effect on the unique number.

  Then

  A single decimal number of entry: 100

  Convert 32 bit hexadecimal string with the low byte first: 0000 42 8

  Anyone have any ideas?

  Thank you

  Slightly lighter, try to cast U32 and exchange words. Same difference.

  (apparently, exchanging words is a NOOP for SGL, but still accepts SGL without constraint. Interesting...)

  

• Convert a decimal number to a string

  I work with a gas mixer and I try to transmit data rates. The mixer takes only decimal values, for example, if you want to 2500 cc debit you must pass it 2500.0. I tried to use the function of decimal string number and do a type cast but I get an error every time machine. The only thing that works is by using a control of the chain and entering the value, but I would like to do it with a digital command. Someone at - it tips or advice?

  

  Note that you have provided only a sample size. In addition, 2500.0 isn't a decimal number, it is a floating point value.

  It is also not clear if how you talk to the machine. You said that you used a Type Cast. For what? How do you communicate with the machine?

• The hexadecimal string to decimal content content

  I write a code in LabVIEW to convert MBus data for some energy meters.

  Apparently the meter that I use sends the data as a string in hexadecimal format, however after correctly parking that string in hexadecimal format, the real value is the decimal number in this hexadecimal string without conversion.

  Example:

  -Response of the meter (String in hexadecimal display):

  68 37 37 68 08 07 72 89 12 13 67 A7 32 04 04 00 00 00 00 0C 06 09 58 02 00 0C 14 39 13 79 00 0B 2D 47 00 00 0 B 3 B A 30 32 00 5-0 HAS 81 03 0A 5TH 68 0 A 03 62 13 00 0F 21 04 00 00 20 86 16

  -After parking, I get 22 bytes to 25 (09 58 02 00) in the right order, i.e. 09 58 00 02 meaning 25 809 MWh.

  This means that I need to transfer sort the string in hexadecimal numbers to display a decimal format and divede by 1000 to get the correct value in MWh.

  I tried to use the Type Cast and Conversion of string without success. Can someone please help me find a solution?

  Best regards.

• Hexadecimal string to HEXADECIMAL number

  Hello Experts,

  I just stuck in a simple problem. in fact I'm having an array of string HEX I want to convert it to HEX number format, I am looking for this conversion. It's that simple, but I can't do this job. Please see the image to join for more understanding.

  

  Soon harry and thnaks in advance

  Harry,

  You can do this (and many other conversions from string to a number) with analysis of the chain. %x indicates LabView input data are hexagonal. There are also a lot of string functions to a number (for example ' in hexadecimal string to the number") which could be faster if you do this 100 000 times in loop, but analysis chain will solve 99% of your problems.

• Number of allocations of memory of hexadecimal string

  I am convert a string to a byte array and then converting this array of bytes into a hexadecimal table using the built-in primitive like this

  

  What is the best way for a performance? When I run the DETT I see multiple memory allocations. I think that one for each element of the array. I think it has to do with the point of constraint. Also, it happens only if I connect to the chain of the indicator. If I run this without the indicator chain I don't see not all memory allocations. (Perhaps LabVIEW do not know the code because I don't do anything with the result)

  I just got the DETT and I'm not very sure of how LabVIEW allocates memory. But I do a test by running this code

  

  I see not all memory allocations in the DETT as I do with the number of hexadecimal string.

• Converts a hexadecimal string to ASCII by VBAI

  Good day, experts, OR the

  I would like to ask for help on the stage of the VBAI calculator. Is there a way I could convert a hexadecimal string to ASCII character? For example 25 (Hex) to %(ASCII) or, if not in the calculator to other methods? I'll have to send data via TCP/IP later.

  Thank you very much
  Andrei K.

  Now I understand what you want. You can actually do from TCP step. First of all, you need get the length of the string in a digital as you did in step of the calculator, but then you can send this digital as a hexadecimal string of ascii to TCP step. To do this, have the length of the string as a numeric result in the return of calculator. In the TCP step, add a "Write" command and insert a result. Select the digital output of the step of the calculator and U8 of the data format. You can use the display/Hex Normal display to view the data that will be sent, and when displaying normal view, you can see that it is a '%' value when length is 37. See the attached screenshot to see how I did it.

  Hope this helps,

• Convert a hexadecimal string to byte array

  Hello

  I would like to convert a hexadecimal string (e.g. 0x156FD18A4) into an array of bytes, the problem is that I don't have any delimiter (for example 15 6F 8 a 4 D1) so I can't use the worksheet to an array of strings, I tried to do something on my own, but everything seems to be too complicated is there an appropriate way clean and neat to achieve what I want? (or maybe a clever trick to add delimiter every two characters in my original string)

  Thank you!

  for a serial communication, I need to send byte-code in an ascii hexadecimal string. When I use the constants and send them by VISA to the COM port it works fine, but if I use converters numbers it doesn't. Can someone show me what I'm doing wrong?

  Since your string indicator is set to hexadecimal display, it seems you want to a hexadecimal string, a single byte/number.

  (You are currently using a hexadecimally format string, composed exclusively of ASCII of the 2 characters/byte "0.F" characters.) This is not what you want!).

  Here is another solution using type conversion:

  

• Hexadecimal string to numeric value

  Hello

  I have a really (I think) a fundamental problem of trying to convert between a hexadecimal number to a 'digital constant' value so I can calculate certain things.

  The situation is: I'm able, a VISA series, a distance of an ultrasonic sensor reading. His current reading in an "indicator of string" ordinary put to a hexadecimal display. About 50 cm from distance with the ultrasonic at a wall sensor, I can measure "0032" as my display hex - what is optimal, 32 in hexadecimal is 50.

  However, my problem is, how do I now go to the conversion of this 0032 in hexadecimal in a usable digital/decimal numbers?

  Thanks heaps for you help.

  I'm trying to communicate through a circulation bath series, but it requires that all orders as a hexadecimal string.  I generate a portion of the string as a constant, but I need to convert a decimal point and add it at the end of the string.  I can convert the decimal to hexadecimal very well, but when I concatenate the strings is not hex ASCII format.  I tried a number of different tracks but am not having success.  Any help out there?

  Too bad.  I have it.  Just need to convert in I16 then catalogued for hex.

• Conversion to hexadecimal string

  Hello world

  I'm using Labview 2012 and receive data on my serial port which I want to convert a hexadecimal string. I have attached a VI that only allows me to convert the first part of the string, but not the rest.

  Does anyone know how to do this?

  PS: I don't want to have just the incator displayed in hexadecimal format, I really need to do a conversion of the string to be able to work around it after.

  Thank you.

  See that red dot on the number of function Hex String in the image of the code, which is your data gets blown into a U64 array.  Yuk.  Drag a loop around the spell function channel number and it is actually a little faster.  Goes against everything you think you know all LV, but it's one of those exceptions.
