There's not so much elixir can do to improve erlang's :math, it's already [implemented](https://github.com/erlang/otp/blob/master/lib/stdlib/src/math.erl)with NIFs. Rewriting it in pure elixir/erlang would only degrade performance.
Other question is why doesn't :math have more functions? BEAM wasn't built for the purpose of number crunching - there's plenty info about slow math in erlang. Although it had improved recently, I'd recommend to look into elixir nx or similar tools. If I understand correctly, they effectively bypass BEAM bytecode/NIFs shenanigans, and compile to native code with vectorization and whatnot. If erlang would add something unholy to its stdlib, you'll be free to ignore it, and keep using your righteous implementation :) ------- Original Message ------- On Thursday, February 23rd, 2023 at 22:23, Julian Somoza <julian.som...@gmail.com> wrote: > Hi, I would like to understand why or what would be the problem with having > our own Math module on Elixir.
