8 File Name: 15.7.2.js
9 ECMA Section: 15.7.2 The Number Constructor
10 15.7.2.1
11 15.7.2.2
12
13 Description: 15.7.2 When Number is called as part of a new
14 expression, it is a constructor: it initializes
15 the newly created object.
16
17 15.7.2.1 The [[Prototype]] property of the newly
18 constructed object is set to othe original Number
19 prototype object, the one that is the initial value
20 of Number.prototype(0). The [[Class]] property is
21 set to "Number". The [[Value]] property of the
22 newly constructed object is set to ToNumber(value)
23
24 15.7.2.2 new Number(). same as in 15.7.2.1, except
25 the [[Value]] property is set to +0.
26
27 need to add more test cases. see the testcases for
28 TypeConversion ToNumber.
