Fixed-Point Arithmetic: An Introduction
courses.cs.washington.edunumbers are simple signed two’s complement integers. Contrast this against the Motorola 56k series which performs two’s complement fractional arithmetic, with values always in the range −1≤ x < +1. It is my hope that this material is clear, accurate, and helpful. If you find any errors or inconsistencies, please email me at yates@ieee.org.
