You would have to either: 1. define an instance method on the class of whatever goes before the period, e.g.: class Fixnum def bits_to_bytes # method content here; `self` holds the object under consideration end end OR 2. define a singleton method on the actual object that goes before the period, e.g.: def 8.bits_to_bytes # method content here; `self` also holds the object under consideration end You probably want option #1 since it will work with all Fixnums.
