23    File Name:          15.7.1.js
24    ECMA Section:       15.7.1 The Number Constructor Called as a Function
25                        15.7.1.1
26                        15.7.1.2
27
28    Description:        When Number is called as a function rather than as a
29                        constructor, it performs a type conversion.
30                        15.7.1.1    Return a number value (not a Number object)
31                                    computed by ToNumber( value )
32                        15.7.1.2    Number() returns 0.
33
34                        need to add more test cases.  see the testcases for
35                        TypeConversion ToNumber.
