    ECMA Section:       9.3  Type Conversion:  ToNumber
    Description:        rules for converting an argument to a number.
                        see 9.3.1 for cases for converting strings to numbers.
                        special cases:
                        undefined           NaN
                        Null                NaN
                        Boolean             1 if true; +0 if false
                        Number              the argument ( no conversion )
                        String              see test 9.3.1
                        Object              see test 9.3-1


                        This tests ToNumber applied to the object type, except
                        if object is string.  See 9.3-2 for
                        ToNumber( String object).
