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:
- Strings
Syntax
- Syntax:
- parseNumber string
- Parameters:
- string: String
- Return Value:
- Number
Alternative Syntax
- Syntax:
- parseNumber boolean Template:since
- Parameters:
- boolean: Boolean
- Return Value:
- Number - 0 if false, 1 if true
Examples
- Example 1:
_number = parseNumber "0.125"; // 0.125
- Example 2:
_number = parseNumber "0050"; // 50
- Example 3:
_number = parseNumber "2 abc"; // 2
- Example 4:
_number = parseNumber true; // 1

- (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
