描述

描述:

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.
