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
and generic range iterators.
num is a meta-crate, re-exporting items from these sub-crates:
num-derive is listed here for reference, but it's not directly included
num. This is a
proc-macro crate for deriving some of
Add this to your
[dependencies] num = "0.2"
and this to your crate root:
extern crate num;
This crate can be used without the standard library (
#![no_std]) by disabling
std feature. Use this in
[dependencies.num] version = "0.2" default-features = false
num-bigint crate is only available when
std is enabled, and the other
sub-crates may have limited functionality when used without
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.
rand feature enables randomization traits in
serde feature enables serialization for types in
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.
Release notes are available in RELEASES.md.
num crate as a whole is tested for rustc 1.15 and greater.
num-iter crates are individually tested
for rustc 1.8 and greater, if you require such older compatibility.
