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
# 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.
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.
Releases
Release notes are available in RELEASES.md.
Compatibility
The num-traits crate is tested for rustc 1.8 and greater.
