WebDec 14, 2008 · Fixed-point numbers use the same integer representations, but they assign a different meaning to the bits. We can introduce the idea of fractional bits and a binary point. With integers, your smallest spacing between numbers is 1. If we decide to let a bit represent ½ we now have closer spacing in our system.
