num-traits

Numeric traits for generic mathematics in Rust.

Usage

Add this to your Cargo.toml:

[dependencies]
num-traits = "0.2"

and this to your crate root:

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:

[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. MulAdd and MulAddAssign for f32 and f64 also require std, as do implementations of signed and floating- point exponents in Pow.

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.

Similarly, additional traits making use of associated constants are available with Rust 1.22 and later. Again, the build script automatically detects this, but you can make it mandatory by enabling the associated_consts crate feature.

Releases

Release notes are available in RELEASES.md.

Compatibility

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