Description

Description:
Parses the string, interpreting its content as a floating point number.
This command does not work with strings representing hexadecimal numbers (e.g "0xCF").
parseNumber "512 + 0x2F"; // 512, WRONG! "512 + 0x2F" call BIS_fnc_parseNumber // 559, CORRECT!
Starting whitespaces are discarded, then as many valid characters are used to be interpreted as a number until an invalid character is found then the rest of the string is ignored.
Groups:
Strings

Syntax

Syntax:
parseNumber value
Parameters:
value: String or Arma 3 logo black.png1.50 Boolean
Return Value:
Number - the parsed number, 0 if no valid number was found; in the case of a passed Boolean, 0 if false, 1 if true

Examples

Example 1:
_number = parseNumber "0.125"; // 0.125 _number = parseNumber "0050"; // 50 _number = parseNumber " 42 yes"; // 42 _number = parseNumber "3 or 4"; // 3 _number = parseNumber "either 3 or 4"; // 0 _number = parseNumber "0xCF"; // 0
Example 2:
since Arma 3 v1.50:
_result = parseNumber false; // 0 _result = parseNumber true; // 1 _zeroOneStatus = parseNumber alive player; // 0 if the player is dead, 1 if alive
