84: Implement fmod r=japaric a=P1n3appl3 closes rust-lang/libm#21 I replaced the `isnanf()` function from `fmodf()` with a call to the core function `is_nan()`. If there's a reason we needed to re-implement it then I can change that back. Also I couldn't figure out what to do in `src/lib.rs`. Is the `#[cfg(todo]` that I should be removing the one for `mod_euc()`? If so why is the equivalent one for the `f64` version still there?

libm
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);
}
Not all the math functions are available at the moment. Check the API docs to learn what's currently supported.
