Fixed point integer
The Q notation, as defined by Texas Instruments, consists of the letter Q followed by a pair of numbers m.n, where m is the number of bits used for the integer part of the value, and n is the number of fraction bits. By default, the notation describes signed binary fixed point format, with the unscaled integer being stored in two's complement format, used in most binary processors. The first bit always gives th… 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.
