# num-traits
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.
