Goals
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.
Benchmark
The benchmarks are located in crates/libm-bench and require a nightly Rust toolchain.
