How do we make a benchmark for that? Run it 1000+ times for random floats? But maybe SBCL has faster random as well! Actually, even I have a better random than Elisp: https://dataswamp.org/~incal/emacs-init/random-urandom/ It is more random than `random', using the Linux random. But I didn't compare them in terms of speed. It is a so called dynamic module, that is, not built-in but still written in C. Anyway, I'd be happy to add something `floor' to the benchmarks, for sure! -- underground experts united https://dataswamp.org/~incal
