Abstract
Fixed-point numbers implement floating-point operations using ordinary integers. This is accomplished through clever use of scaling and allows systems without explicit floating-point hardware to work with floating-point values effectively. In this chapter we explore how to define and store fixed-point numbers, how to perform signed arithmetic with fixed-point numbers, how to implement common trigonometric and transcendental functions using fixed-point numbers, and, lastly, discuss when one might wish to use fixed-point numbers in place of floating-point numbers.
