File Name: 15.7.2.js
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.
