Description

Description:

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.

For clarity, the output of parseNumber only reflects numbers found before the first non-numeric character.

When trying to parse a string from an array, be sure to properly use parenthesis.
parseNumber _array select 0; //""Error Generic error in expression"", position: _array |#|select 0 hint format["%1", parseNumber _array select 0]; //"Error Generic error in expression", pos: _array |#|select 0
parseNumber (_array select 0); //No error
