    ECMA Section:       15.1.2.3 Function properties of the global object:
                        parseFloat( string )

    Description:        The parseFloat function produces a number value dictated
                        by the interpretation of the contents of the string
                        argument defined as a decimal literal.

                        When the parseFloat function is called, the following
                        steps are taken:

                        1.  Call ToString( string ).
                        2.  Remove leading whitespace Result(1).
                        3.  If neither Result(2) nor any prefix of Result(2)
                            satisfies the syntax of a StrDecimalLiteral,
                            return NaN.
                        4.  Compute the longest prefix of Result(2) which might
                            be Resusult(2) itself, that satisfies the syntax of
                            a StrDecimalLiteral
                        5.  Return the number value for the MV of Result(4).

                        Note that parseFloate may interpret only a leading
                        portion of the string as a number value; it ignores any
                        characters that cannot be interpreted as part of the
                        notation of a decimal literal, and no indication is given
                        that such characters were ignored.

                        StrDecimalLiteral::
                        Infinity
                        DecimalDigits.DecimalDigits opt ExponentPart opt
                        .DecimalDigits ExponentPart opt
                        DecimalDigits ExponentPart opt
