num

crate documentation minimum rustc 1.15 Travis status

A collection of numeric types and traits for Rust.

This includes new types for big integers, rationals, and complex numbers, new traits for generic programming on numeric properties like Integer, and generic range iterators.

num is a meta-crate, re-exporting items from these sub-crates:

Repository Crate Documentation
num-bigint crate documentation
num-complex crate documentation
num-integer crate documentation
num-iter crate documentation
num-rational crate documentation
num-traits crate documentation
(num-derive) crate documentation

Note: num-derive is listed here for reference, but it's not directly included in num. This is a proc-macro crate for deriving some of num's traits.

Usage

Add this to your Cargo.toml:

[dependencies]
num = "0.2"

and this to your crate root:

extern crate num;

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]
version = "0.2"
default-features = false

The num-bigint crate is only available when std is enabled, and the other sub-crates may have limited functionality when used without std.

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.

The rand feature enables randomization traits in num-bigint and num-complex.

The serde feature enables serialization for types in num-bigint, num-complex, and num-rational.

The num meta-crate no longer supports features to toggle the inclusion of the individual sub-crates. If you need such control, you are recommended to directly depend on your required crates instead.

Releases

Release notes are available in RELEASES.md.

Compatibility

The num crate as a whole is tested for rustc 1.15 and greater.

The num-traits, num-integer, and num-iter crates are individually tested for rustc 1.8 and greater, if you require such older compatibility.
