   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.
