A port of MUSL's libm to Rust.


The short term goal of this library is to enable math support (e.g. sin, atan2) for the wasm32-unknown-unknown target (cf. rust-lang/compiler-builtins). The longer term goal is to enable math support in the core crate.

Already usable

This crate is on crates.io and can be used today in stable #![no_std] programs.

The API documentation can be found here.


The benchmarks are located in crates/libm-bench and require a nightly Rust toolchain. To run all benchmarks:

cargo +nightly bench --all
