In the 2000's I wrote games on MS PocketPC. It had emulated floating point, which was painfully slow for games. Most games could do with just integers. Once I made some physics based games, I implemented fixed point indeed, and it went more or less fine. A 3D engine in fixed point (which I never fully finished) gave me a lot of headaches. So glad all those devices have proper floating point and a gpu's.
