Numeric traits for generic mathematics in Rust.
Add this to your
[dependencies] num-traits = "0.2"
and this to your crate root:
extern crate num_traits;
This crate can be used without the standard library (
#![no_std]) by disabling the default
std feature. Use this in
[dependencies.num-traits] version = "0.2" default-features = false # features = ["libm"] # <--- Uncomment if you wish to use `Float` and `Real` without `std`
Real traits are only available when either
libm is enabled.
libm feature is only available with Rust 1.31 and later (see PR #99).
FloatCore trait is always available.
f64 also require
libm, as do implementations of signed and floating- point exponents in
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.
Release notes are available in RELEASES.md.
num-traits crate is tested for rustc 1.8 and greater.
