This is so cool! I'm feeling inspired to build out a CPU in factorio, and i hadn't really thought of a raycaster but i'm definitely going to try to build toward something similar :)

I was surprised how accurate the approximation was. It's almost like it was made my Ramanujan or something.

If you're interested, I've made sin(x) with precision 10^-9 using taylor series. Computation of sin(pi/3) takes 29 ticks.
