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.

(A3 1.26)It only detects the first occurrence of a number in the string, return 0 by default. parseNumber "2s4f"; // 2 parseNumber "s2f4"; // 0 parse config or code, currently BIS_fnc_parseNumber, occurrence is only limited with number, return -1 by default. {s3s4f} call BIS_fnc_parseNumber; // -1

This command does not work with strings representing hexadecimal numbers: parseNumber "0xCF"; //Returns 0
