| /** |
| File Name: 15.7.4.js |
| ECMA Section: 15.7.4 |
| |
| Description: |
| |
| The Number prototype object is itself a Number object (its [[Class]] is |
| "Number") whose value is +0. |
| |
| The value of the internal [[Prototype]] property of the Number prototype |
| object is the Object prototype object (15.2.3.1). |
| |
| In following descriptions of functions that are properties of the Number |
| prototype object, the phrase "this Number object" refers to the object |
| that is the this value for the invocation of the function; it is an error |
| if this does not refer to an object for which the value of the internal |
| [[Class]] property is "Number". Also, the phrase "this number value" refers |
| to the number value represented by this Number object, that is, the value |
| of the internal [[Value]] property of this Number object. |
