Several different approaches to performing the modulus operation are presented. In one, a method of performing the modulus operation upon a dividend and a divisor within a limited range is discussed. The method involves storing a reference value, receiving a dividend value, and calculating a number of derived inputs. Each of the derived inputs corresponds to the dividend value minus the reference value, and is then further modified by a multiple of the divisor. Using the divisor to select between these derived inputs provides the answer.
