[![Build Status](https://github.com/wrengr/exact-combinatorics/workflows/ci/badge.svg)](https://github.com/wrengr/exact-combinatorics/actions?query=workflow%3Aci)
[![Dependencies](https://img.shields.io/hackage-deps/v/exact-combinatorics.svg?style=flat)](http://packdeps.haskellers.com/specific?package=exact-combinatorics)

Efficient exact computation of combinatoric functions.


## Install

This is a simple package and should be easy to install via the
standared method:

    $> cabal install exact-combinatorics


## Portability

An attempt has been made to keep this library as portable as possible.
It is entirely Haskell98 with the exception of one use of BangPatterns.
BangPatterns are supported in GHC as far back as [version
6.6.1][ghc-bangpatterns], and are also supported by [JHC][jhc-bangpatterns]
and [UHC][uhc-bangpatterns]. As of 2010, they were [not supported
by Hugs][hugs-bangpatterns]; but alas Hugs is pretty much dead now.
