| File Name: number-003.js |

| ECMA Section: 15.7.4.3.1 Number.prototype.valueOf() |
| Description: |
| Returns this number value. |
| |
| The valueOf function is not generic; it generates a runtime error if its |
| this value is not a Number object. Therefore it cannot be transferred to |
| other kinds of objects for use as a method. |
