String to Number

If there a function for GDL that turns a string into a number or extracts part of a string to be a number?

Thanks in advance.

Check out STR() in the GDL Reference Manual. It has several uses and variables.

This came straight from the Archicad/GDL Help. STR requires a numerical expression and changes it to a string. I'm looking for a Function that turns a String into a Number.

STR (numeric_expression, length, fractions)
STR{2} format_string, numeric_expression [,
exta_accuracy_string])

The first form of the function creates a string from the current value of the numeric expression. The minimum number for numerical characters in the string is length, while fractions represents the numbers following the floating point. If the converted value has more than length characters, it is expanded as required. If it has fewer characters, it is padded on the left (length>0) or on the right (length<0).
Example:

A=4.5
B=2.345
TEXT2 0, 2, STR(A, 8, 2) ! 4.50
TEXT2 0, 1, STR(B, 8, 2) ! 2.34
TEXT2 0, 0, STR(A*B, 8, 2) ! 10.55
