Floating point arithmetic is a historical curiosity. No, floats still are noticeably slower & obviously dirtier, sloppier than a pure integer, combinatorics approach (the mere float/int conversion is already unbearable). Yes, there are empires built on the inefficiency of floating point arithmetic e.g., NVIDIA & such. You don’t need floats, / or * in a 3-D renderer. You don’t even need the weaklings’ parallelism. There are existence proofs.
