# `libm`
A port of [MUSL]'s libm to Rust.
[MUSL]: https://musl.libc.org/
## Goals
The short term goal of this library is to [enable math support (e.g. `sin`, `atan2`) for the
`wasm32-unknown-unknown` target][wasm] (cf. [rust-lang/compiler-builtins][pr]). The longer
term goal is to enable [math support in the `core` crate][core].
[wasm]: https://github.com/rust-lang/libm/milestone/1
[pr]: https://github.com/rust-lang/compiler-builtins/pull/248
[core]: https://github.com/rust-lang/libm/milestone/2
## 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](https://docs.rs/libm).
