+   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.
