Generic `Rational` numbers for Rust.

## Usage

Add this to your `Cargo.toml`:

```toml
[dependencies]
num-rational = "0.2"
```

and this to your crate root:

```rust
extern crate num_rational;
```

## Features

This crate can be used without the standard library (`#![no_std]`) by disabling
the default `std` feature.  Use this in `Cargo.toml`:

```toml
[dependencies.num-rational]
version = "0.2"
default-features = false
```

Implementations for `i128` and `u128` are only available with Rust 1.26 and
later.  The build script automatically detects this, but you can make it
mandatory by enabling the `i128` crate feature.

## Releases

Release notes are available in [RELEASES.md](RELEASES.md).

## Compatibility

The `num-rational` crate is tested for rustc 1.15 and greater.
