How to get 12 from "12"

GiriBabu

Hi all. I need to get  Value of string without quatations. For example 12 from "12" .

  •  I solved this problem through the command stringToSymbol(). Now i want to create string for a value in variable. See below code

             number=12(actually this number varies)     

          strcat("fps" number)

    I don't want like strcat("fps" "12") because 12 is varies for every time.
  • Actually stringToSymbol will not convert it to a number, but to a symbol. You can use atoi() for an integer, atof() for a float, or cdfParseFloatString if it uses suffix notation (e.g. "1.2u")

    To go the other way, use sprintf():

    sprintf(varName "fps%d" number)

    Or if you don't need to assign to a variable but just want to use the return value:

    sprintf(nil "fps%d" number)

    This has come up several times on the forums, I believe.

  • One way to do is as follows: =>evalstring("12") =>12

  • Yes, but the methods that Andrew pointed out are better.  Here's why: The "evalstring" approach can be used to generally evaluate some SKILL expression in a string format, but what if the string happened to contain the word "exit" rather than a number - evalstring would cause the session to close.  So although this approach could be used, I would recommend using one of the earlier noted methods (i.e. atoi, atof, cdfParseFloatString).

    Regards,
