Parses a string as an number.
Examples:
variable tString as String put "5.6" into tString parse tString as Number -- the result is 5.6
variable tResult as optional String variable tNum as optional Number parse "aaaa" as Number into tNum if tNum is nothing then put "unable to parse string" into tResult end if
Use ParseStringAsNumber when you want to interpret text numerically. The result is nothing if parsing was not possible.
