# num-traits [![crate](https://img.shields.io/crates/v/num-traits.svg)](https://crates.io/crates/num-traits) [![documentation](https://docs.rs/num-traits/badge.svg)](https://docs.rs/num-traits) [![minimum rustc 1.60](https://img.shields.io/badge/rustc-1.60+-red.svg)](https://rust-lang.github.io/rfcs/2495-min-rust-version.html) [![build status](https://github.com/rust-num/num-traits/workflows/master/badge.svg)](https://github.com/rust-num/num-traits/actions) Numeric traits for generic mathematics in Rust. ## Usage Add this to your `Cargo.toml`: ```toml [dependencies] num-traits = "0.2" ``` ## 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 # features = ["libm"] # <--- Uncomment if you wish to use `Float` and `Real` without `std` ``` The `Float` and `Real` traits are only available when either `std` or `libm` is enabled. The `FloatCore` trait is always available. `MulAdd` and `MulAddAssign` for `f32` and `f64` also require `std` or `libm`, as do implementations of signed and floating- point exponents in `Pow`. ## Releases Release notes are available in [RELEASES.md](RELEASES.md). ## Compatibility The `num-traits` crate is tested for rustc 1.60 and greater. ## License Licensed under either of * [Apache License, Version 2.0](http://www.apache.org/licenses/LICENSE-2.0) * [MIT license](http://opensource.org/licenses/MIT) at your option. ### Contribution Unless you explicitly state otherwise, any contribution intentionally submitted for inclusion in the work by you, as defined in the Apache-2.0 license, shall be dual licensed as above, without any additional terms or conditions.
