Number.parseFloat

The Number.parseFloat() method parses a string argument and returns a floating point number. This method behaves identically to the global function parseFloat() and is part of ECMAScript 2015 (its purpose is modularization of globals).

Parameters

value: The value you want to parse.

Return value

A floating point number parsed from the given value. If the value cannot be converted to a number, NaN is returned.

    Number.parseFloat = parseFloat;
}
