libm 0.1.4

libm in pure Rust

libm

Build Status

A port of MUSL's libm to Rust.

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-nursery/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 like this:

#![no_std]

extern crate libm;

use libm::F32Ext; // adds methods to `f32`

fn foo(x: f32) {
    let y = x.sqrt();
    let z = libm::truncf(x);
}
