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).




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.


Please see parseFloat() for more details and examples.
