  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.
