• Adds a zero number to string conversion

  So I have a 0 in int format. I want to convert to a string so that it indicates "00". Is there an easy way to do it in labview? or if I have 1 to int, I want to convert it to a string value of "01." Help?

  Thank you!

  You just need to use % 02d as the format specifier with your function in the Format string. If you move your mouse over the function and right click, you can select "modify Format strings. The popup will provide assistance.

• Add number of zeros for exhibitor in number of string range

  Hi all

  I want to read a string and convert it to a number that the string is in the form 2.000000E + 00, add a number to it and convert it back to a string in the same format. I can read the string and to convert a number, I'm just not sure since the help files how to convert a string to the specific format. 'Number of exponential string' using gives me the correct number in almost the correct format, just missing the extra number in the exponential.

  For example

  2.000000E + 00-> string to number-> add 0.5-> number to String-> 2.500000E + 0

  Missing the last zero I need for orders of stage position. I can change the string to add, but as the position values will vary, how the chain gets published would be inconsistent. I need preferably a way to convert any number in this format.

  Thank you

  Here's the solution I came up with that.  Not really pretty, but it works.

  

• string conversion appropriate type based on the content of string

  Hello

  I have a CSV with string values, and I want to assign them to good type in labview, then assing them to some pre-existing teststand properties.

  I think a particular way in a digital chain of detection should be in labview somewhere, but I can't seem to find it.  There is certainly decimal string number and string of fractional number, but an error during their passage of a string like "blah".  They just return 0.

  So my main challenge here is to feel a digital channel, either with a single point decimal or not and the impression that it is a 'number '.

  Example:

  Takes the string->

  1.234-> is the number

  1234-> is the number

  192.168.1.12-> is not a number

  I could write a vi to do this, but I was wondering if it wasn't already obvious tool in labview, which is escaping at that time.  I don't like to reinvent the wheel, even for something so simple.

  Thank you

  In the more general case, you must also be able to properly analyze, for example - 10e6, 85.83E - 3 and such good number to floating point. Also your last example is basically a number U32, just formatted in the style of IP address.

  You must use 'analysis of the string' %f format and NaN as a default value. Then also check if the string is an empty string. If this isn't the case, then it is not a number according to your narrow definition.

• Number in hexadecimal string conversion problem

  Hello

  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?

  Windows XP SP3, LV 8.5.1

  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:

  

• String conversion number

  Hi all

  I need to convert the string like "-73.28" to the number - 73.28. With decimal string to number Vi I get only - 73,00 output with "-73.28" Dim input As string. What I've done wrong? How to get the required results? Also, note that it must be. the number of output!

  Thank you!

  Hi Nina,

  Firstly: have the decimal separator ',' in a digital indicator is just for aesthetic purposes, you can always calculate using the value...

  (1) you can change the settings of the operating system (Win: settings regional aka regional Einstellungen). I do this for all my computers as it seems "natural" for me when working with scientists/measurement data

  (2) you can move LV to ignore the decimal separator system settings - you will find in the dialog box options...

  But when using properly formatted output functions you do not need to change any setting...

• In Keithley 2410, string number read voltage conversion

  Hello

  I want to drive the current and voltage with Keithley 2410 to read.

  However, I can read the correct voltage value in the screen of the device, I can't read the correct voltage value in the display of laboratory program. The problem occurs while the voltage read (string) is converted to a number. I use String Fract/Exp number for this. However, I can read only the first digit of the value. for example, in the screen of the device, I read 1.3784e - 5 (the actual voltage value), in the indicator of software, I have read only 1.

  I am new to laboratory. can someone help me on this you problem.

  My Magic 8-Ball says that your system settings have the comma is the decimal separator.  The Keithley instrument will always be the decimal point as the decimal separator.  Fortunately, there are a Boolean input on the Fract/Exp to string number which affects whether to use the system separator.  Make sure you set that to FALSE.

• string conversion number in Unix

  I'm extremely sorry to post this here. I googled a Unix category for this post here. But could not find one.
  I have a string in Unix. I need to remove characters from the string.

  var=2012/03/26
  I need to remove the special char's('/') from the string. It should be 20120326. 

  I tried expr substr, but did not get the result.
  
  Sorry again to post in the wrong category.

  Try

  newvar=`echo $var|sed 's/[^0-9]//g'`
  

  Who's going to shoot anything that isn't a digital character in the string in the variable ${newvar}.

  Seems you watch a channel that will (eventually) be interpreted as a date, what happens when the string 'date' lack of zeros? It won't be pretty.

• Actual number of string in table

  Hello

  I want to read real numbers to a text file and put them in a table.

  The problem is that the precision of the number is not displayed. It is converted in full.

  There is an example similar to http://forums.ni.com/t5/LabVIEW/Text-string-to-integer-array-with-keeping-order-in-text-string/m-p/1...

  I couldn't transfer the number in the array of strings in a digital picture.

• Channel of String conversion to the data channel

  I have a problem I tried to accomplish through a. The URI of the file but can seem to make it work good for me.  I have an original data channel are in TEXT format and the data in the channel are the phone number in the format 6667779999 or 4343. Can someone help me with a suggestion of script to convert this. Most of my ATTEMPTS end with a 66.67779e5.  Can be simple but I can just figure it out.

  Thank you J

  Hello J,

  A number such as 66.6778888e5 can be shown as 6667778888 in a DISPLAY box or table or text REPORT or a axis of REPORT graph by using the display correct format string - in this case "d".  Where do you 6667778888 number appears like this in DIAdem, exactly?  If you want to see in a BULLETIN Board, you will need to choose the option button 'Selected channels' first in the configuration dialog box, and only then will you be able to choose a format string to display such as "d" for this column.

• mixed number a string does not properly

  I am in a position some parameters of oscillsocpe. I need to write these values in text file which I use write to the spreadsheet, but what happens is that it is always written zero value to the file, debugging I found that converting the number to a string, it is still writng zero string indicator, separately, I used that number to fractional chain indicator and then it shows always zero out of string I'm not why it's happening.

  Attached below is the code.

  It's simple. When you convert a read nsec, you must of course greater precision of 2 decimal places. Why do you not use number of exponential or engineering.

• Convert number to string in function, spell training?

  I saw a few posts asking how to convert a hexadecimal string to a number, but I saw nothing in regard to going the other way - how to convert a new number into a hexadecimal string. Can TestStand convert a number to a hexadecimal string in a function?

  Here's what I'm trying to do (Locals.CryTuneHex is a string containing a hexadecimal value represented and Locals.Freq_Meas is a digital):

  Locals.CryTuneHex = Val ("0 x" + Locals.CryTuneHex) + round (((320000 - Locals.Freq_Meas)/0.065),4)

  or in simpler terms:

  Locals.HexString = Locals.DecimalNumber

  I need to convert the right side of the equation (which is a decimal number) to a hexadecimal string in order to to store in the string variable on the left side of the equation. Is this possible? In my view, there are a Str() operator to convert to a string, but I need in hex, not only a string representation of the decimal number.

  Thank you!

  Pass a format to Str, like the people of the country. HexString = str (Locals.Number, "%x")

  To play with format strings, create a local number, right-click and select the Digital Format, and then select Hex to Type and watch how the format string varies when you change options.
