Description
- Description:
- An SQF equivalent of C++ atof function. 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. - Groups:

Syntax
- Syntax:

Alternative Syntax
- Syntax:
- parseNumber boolean Template:since
- Parameters:
- boolean: Boolean
- Return Value:
- Number - 0 if false, 1 if true
