107: add an implemetation of asin r=japaric a=japaric Fixes #7 Additonally adds inline functions for macros dealing with low and high words of f64s to the root module. Also, the muslc code used a hexdecimal float. This shouldn't be needed because Rust implements floating point parsing well. --- rebased version of #95 closes #95 Thanks @vjackson725 for the original PR!

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.
