string

The value to parse, coerced to a string. Leading whitespace in this argument is ignored.

A floating point number parsed from the given string.

Or NaN when the first non-whitespace character cannot be converted to a number.

This method has the same functionality as the global parseFloat() function:

Number.parseFloat === parseFloat; // true

Its purpose is modularization of globals.

See parseFloat() for more detail and examples.
