Numeric traits for generic mathematics in Rust.

## Usage

Add this to your `Cargo.toml`:

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

and this to your crate root:

```rust
extern crate num_traits;
```

## 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-traits]
version = "0.2"
default-features = false
```

The `Float` and `Real` traits are only available when `std` is enabled. The
`FloatCore` trait is always available.

## Releases

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

## Compatibility

The `num-traits` crate is tested for rustc 1.8 and greater.

Bump rustc to 1.8 and revamp all CI This bumps the minimum rustc to 1.8.0, "fixing" #257. I normally consider this a breaking change, but we were already broken due to external factors, for which I couldn't find a workaround. This adds 1.15.0 to the CI matrix to build stable num-derive. We still need nightly to run its tests though, because of compiletest_rs, and dev-dependencies can't be optional. The testing scripts are moved from .travis/ to ci/, as they don't really need to be hidden. It's also now consolidated into one test_full.sh which considers $TRAVIS_RUST_VERSION as needed. 2017-02-10 00:09:48 +00:00
