    File Name:          15.7.1.js
    ECMA Section:       15.7.1 The Number Constructor Called as a Function
                        15.7.1.1
                        15.7.1.2

    Description:        When Number is called as a function rather than as a
                        constructor, it performs a type conversion.
                        15.7.1.1    Return a number value (not a Number object)
                                    computed by ToNumber( value )
                        15.7.1.2    Number() returns 0.

                        need to add more test cases.  see the testcases for
                        TypeConversion ToNumber.
