Description
Function Str2Num returns the specified string as a numeric value.
FUNCTION Str2Num(
s :STRING) : REAL;
def vs.Str2Num(s): return REAL
Parameters
s STRING Source string.
Remarks
(Orso, 18 Nov. 17): Please be careful with overriding standard routines.
Author unknown:
FUNCTION Str2Num(str :STRING) :REAL; {This over-rides the built-in FUNCTION, and is more robust because it handles unit marks in the string, while the built-in FUNCTION does not. Returns zero if it fails, which of course does not unambiguously indicate failure, but it's the same thing that Str2Num returns on failure (without the warning). If you need to know whether or not the FUNCTION succeeded, you shouldn't be using Str2Num, but ValidNumStr instead.} VAR num :REAL; BEGIN Str2Num := 0; IF ValidNumStr(str, num) THEN Str2Num := num; END;
Example
VectorScript
numValue:=Str2Num('235.44');
