num-traits

num-traits

Numeric traits for generic mathematics in Rust.

Usage

Add this to your Cargo.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:

[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 libm feature is only available with Rust 1.31 and later (see PR #99).

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.

Compatibility

The num-traits crate is tested for rustc 1.31 and greater.
