Hi,

This seems to be a funny Q16.16 experiment.
It shows that an integerish Hack can do
floatish stuff, by using binary fixpoint:

Raytracing on the Hack computer

That it uses Rust is arbitrary. Feel free
to do it in C, C++, FORTRAN or Java. I guess
these languages all have basic arithmethic,

right? Maybe not a long jump always?

Bye
