+   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.
