From my experience, the absolute magicians in fixed point math were the 8-bit and 16-bit video game designers. I was in awe of the optimizations they did. They made it possible to calculate 3D matrix maths in real time, for example, in order to make the first flight simulators and first person shooter games.

Redefining degrees to be 2pi = 256 was a pretty clever trick.
