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