Performance / Benchmark

[jbirnick]

Hey, I'm about to implement an algorithm where arbitrary-precision floats (and ints) are at the heart.

That's why I'm currently looking for the best library to use for that. In particular, I'm still deciding whether I should use Rust or C++. I would prefer Rust, but if the Rust libraries are not there yet than I have no choice but to use C++.

I found your library and it looks interesting! I saw that you wrote that efficiency is only the second focus. That's fine, but I would be interested if you have an idea of how it (and maybe even how rug and asto-float) compares to GMP and MPFR?

I couldn't find any benchmarks, and I would just be interested in the order of magnitude of how much efficiency I would have to give up.

I haven't implemented a fair comparison for float arithmetics, but I would say the library is currently roughly 2x - 5x slower than MPFR, depending on what operations you want to use.
