Inputs/Outputs

  • cstr.png string —

    string is the input string the function scans.

  • cstr.png format string —

    format string specifies how to convert the input arguments into value.

    Use the format string syntax.
  • cdbl.png default (0 dbl) —

    default is the numeric representation for value.

    The default is a double-precision, floating-point value of 0.
  • istr.png output string —

    output string is the remaining characters in string after the match or string if there is no match.

  • idbl.png value —

    value is the converted value or the value in default if there is no match.

    If value is an integer, it can overflow if the input is out of range. In that case, value is set to the maximum or minimum value for the data type. For example, if the input string is 300 and the data type is an 8-bit signed integer, LabVIEW sets the value to 127.
