+ File Name: number-003.js
+ Corresponds To: 15.7.4.3-3.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.
