  24     ECMA Section:       15.7.2 The Number Constructor
  25                         15.7.2.1
  26                         15.7.2.2
  27
  28     Description:        15.7.2 When Number is called as part of a new
  29                         expression, it is a constructor:  it initializes
  30                         the newly created object.
  31
  32                         15.7.2.1 The [[Prototype]] property of the newly
  33                         constructed object is set to othe original Number
  34                         prototype object, the one that is the initial value
  35                         of Number.prototype(0).  The [[Class]] property is
  36                         set to "Number".  The [[Value]] property of the
  37                         newly constructed object is set to ToNumber(value)
  38
  39                         15.7.2.2 new Number().  same as in 15.7.2.1, except
  40                         the [[Value]] property is set to +0.
  41
  42                         need to add more test cases.  see the testcases for
  43                         TypeConversion ToNumber.
