• "Decimal string to Number.vi" bug in LabVIEW 2009 SP1

  The "decimal string to Number.vi' seems to be the conversion of the input data in the type int32 internally even when the input tape in vi data is expanded floating point (no points of constraint).  This is causing me grief.  See attached vi

  This bug is still present in LabVIEW 2010?

  Thank you

  Richard Ballantyne

  There is no bug. You use the wrong function (see Help) If you want a floating point output. Use Fract/Exp string to a number.

• The decimal string to number Conversion, cutting necessary zeros

  I'm new to the forum, but have been using labview for awhile. Finally found something that really puzzled me, hope I can find someone who is smarter than me! It may be something obvious too, but here goes. The attached vi is the cause of the error. I have a serial number I need to convert a decimal string into a number, I use later the number of "math" so he need as a number. The system always receives a serial number of 6 characters (ie. 123456), but today the system has received a serial number with two leading figures of the scale (ie. 003456) zeros. This compensation of all the bells of alarm stream (sent 4 digits), but the error found that started the 'intelligence' at the beginning of the monitoring program. I would like to know if there is a way to force the zeros in the decimal number in string to not shave off the coast of the 6-digit value above.

  Ideas or comments, thank you!

  The problem is not the string functions.  This is the display format for your digital indicator.  Change the properties on that.

  

• Hi, I have two decimal strings, each of them contains the numbers change over time. I want to plot them on the graph XY, a string for each axis. Can you show me how do?

  Hi, I have two decimal strings, each of them contains the numbers change over time. I want to plot them on the graph XY, a string for each axis. Can you show me how do?

  This is not a formula, but a constant simple schema of a table complex. Wire remains, then do a right click of the terminal of the initializer of the feedback node and select "create constant. That should do it.

• String ASCII to decimal string and its sum

  Hi all

  I am a beginner in Labview and this is my first post on the forum.

  I get a package series "1200F" on a MCU COM port. These are all ASCII characters.

  I want to convert all of these ASCII characters into decimal numbers and add their decimal values to get the sum. So I took the ASCII string in a table using "Array of strings of bytes" and then typecast this constant using type U8. I put this in a loop and collects the decimal value using the Array function build. So I "Add elements of an array" function to add these decimal values to get the sum.

  The problem is that for the input string, I am able to get the sum of "1200" only. At the time wherever I type the last character ASCII F, the sum does not. I see that when the sum exceeds 255 it resets again from 0. I have attached the VI for reference.

  Any help would be appreciated.

  

  Convert 32 to avoid the limitation 255 of U8.

• Insert the record with the decimal string?

  I want to insert a record with commas, as the below:
  

  INSERT INTO TABLEA(CITY) VALUES('ALBANY,NEWYORK,TROY')

  Is there a way we can insert commas in the table?

  This statement has been inserted

  What is your question.

  SQL> INSERT INTO TABLEA(CITY) VALUES('ALBANY,NEWYORK,TROY') ;
  
  1 row created.
  

• 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?

• 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

  followed by a decimal string to number.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).

• String is rounded off the coast

  I used:

  http://forums.NI.com/T5/LabVIEW/how-to-read-serial-data-from-Arduino-using-LabVIEW-visa/TD-p/1497866...

  VI and did the editing. Use of LabVIEW to arduino. I already have the data I needed. I get a data of 33.75 that output will be 34. What I need is to get the data with the decimal point without rounding downwards or upwards.

  Ive attached the VI.

  Help, please! Thank you!

  Use a string of Frac/Exp number instead of a decimal string to number.  The decimal string number gives you an integer, so it rounds.

• 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...

• To the number of decimal places control user input

  Hey everybody,

  I am all new to LabVIEW and just learn how it works. I was wondering if there was a way to allow user input to change the number of decimal places (the output of my function is infinitely extensible).

  I tried, but it did not work:

  Using a digital input, I appended a string with "%" + '[INPUT]' + 'f' with the number of function concat strings and string functions. I used the resulting string as the formatting string in the value format function.

  This doesn't quite work. The output should be something like "28.274", but instead, it displays "283f. Anyone know why? Is there a better way to do it?

  In addition, attach a picture of the front panel and diagram of block for clarity.

  (Yes, it's homework, but the assignment does not include allowing the user to adjust the number of decimal places, it's just something I would like to add.)

  Get rid of the number 2 for the width of your decimal string number.  It requires a space before a number to a number.  %. 6F is not equal to % .6f.  The string format don't quite understand the first format string.

  (PS.  It helps if you attach your VI.  In this way we can play with what you have rather than trying to recreate it from scratch.)

• String table in full

  Sorry to ask a such simple question here.

  I get a string of numbers such as 11.812. I want to convert this string 11.812 in full. Currently, I tried to use a decimal string to the number, but all I get is 11. I need clarification 11.812.

  Please help thanks! : womanhappy:

  Try using the Fract/Exp to string number function.

• convert integers in equivalent characters in string - character of ASCII code

  I got out of my data and information of the associated string to an array of strings, and then to a spreadsheet file.

  I want to do this by converting an identical string of characters (integers and other numbers).

  I tried Type font with a constant string as the input of type but it DOES NOT WORK.  Instead, I get the ASCII character whose numeric designation corresponds to the integer, for example integer '50' become 'P' capital.

  I want all over '50' string '50 '.

  Please advise, and no, I don't want to make the berries of the clusters.

  I found my answer, but only after the search for 'Number' rather than 'Integer' conversion conversions.

  In the range of programming - number of string - string/number of Conversion - decimal string functions:

  'Converts number to a string of decimal digits less than width characters wide or more if necessary. If the number is floating point, it is rounded up to a 64-bit integer before the conversion. »

• 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

  David J.

  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.
