    ECMA Section:       15.7.2 The Number Constructor
                        15.7.2.1
                        15.7.2.2

    Description:        15.7.2 When Number is called as part of a new
                        expression, it is a constructor:  it initializes
                        the newly created object.

                        15.7.2.1 The [[Prototype]] property of the newly
                        constructed object is set to othe original Number
                        prototype object, the one that is the initial value
                        of Number.prototype(0).  The [[Class]] property is
                        set to "Number".  The [[Value]] property of the
                        newly constructed object is set to ToNumber(value)

                        15.7.2.2 new Number().  same as in 15.7.2.1, except
                        the [[Value]] property is set to +0.

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