Back in the day of 80286's and 80386's there was a popular Fractal generating software that did all calculations in fixed point arithmetic because PCs usually had no FPU back then.

Fractint[1], the site has a certificate error, but otherwise works fine, even the software still gets updated from time to time.

Used it to generate uniform random plasma fields for game textures. Great program!

With the right color map they made a nice sky with clouds. Color cycling them through a smooth full color map was also nice.
