bigfloat-bench

A benchmark of bigfloat libraries for Rust.

This is reworked version of bigint-benchmark-rs.

Benchmark covers rug, num-bigfloat, astro-float, dashu-float (unfortunately, dashu-float doesn't work for some reason and is not present among the benchmark results at the moment, although you can try running benchmark with it included).

Benchmark runs 5 iterations for each task and selects the best result. Each task uses an array of random normal floats with nearly the same precision.

Usage

cargo run --release -- --lib rug --lib num-bigfloat --lib astro-float -n 5 \
                       --task add --task sub --task mul --task div --task sqrt \
                       --task cbrt --task ln --task exp --task pow \
                       --task sin --task asin --task cos --task acos --task tan --task atan \
                       --task sinh --task asinh --task cosh --task acosh --task tanh --task atanh
