Description

Description:

Parses the string, interpreting its content as a floating point number. The command first discards as many whitespace characters as necessary until the first non-whitespace character is found. Then, starting from this character, takes as many characters as possible that are valid following a syntax resembling that of floating point literals, and interprets them as a numerical value. The rest of the string after the last valid character is ignored and has no effect on the behavior of this command. If the first sequence of non-whitespace characters in string does not form a valid floating-point number, or if no such sequence exists because either string is empty or contains only whitespace characters, no conversion is performed and the command returns 0.

Notes

• If the text does not represent a number ("abc" for example), parseNumber will return 0 (zero). It is therefore not possible to use parseNumber to determine if the string contains a valid number or not.

I beg to differ.
_stringNotContainingValidNumber = "abc"; if(parseNumber _stringNotContainingValidNumber == 0 && _stringNotContainingValidNumber != "0") then { comment "INVALID NUMBER"; } else { comment "VALID NUMBER"; }; MulleDK13 09:26, 11 July 2010 (CEST)
