| 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. |
