Readme for fast-arithmetic-0.1.1.2

[back to package description]

fast-combinatorics

This is a library for fast arithmetical functions using ATS, with a Haskell wrapper.

It is intended to supplement (but not replace) arithmoi where speed is important. In particular, this library provides a fast primality check.

Benchmarks

Computation	Version (ATS/Haskell)	Time

`isPrime 2017`	Haskell	497.3 ns
`φ(2016)`	ATS	5.574 μs
`φ(2016)`	Haskell	177.3 μs
`τ(3018)`	ATS	7.962 μs

`ω(91)`	ATS	282.1 ns
`ω(91)`	Haskell	1.194 μs

Building

The Haskell library comes with the C bundled, however you will likely want to build from source if you are hacking on the library. To that end, you can install stack, patsopt, and pats-filter and build with

 $ ./shake.hs

You will also likely want to install GHC as well as cabal.

Documentation

You can find documentation for the Haskell library on Hackage. Unfortunately, there is no documentation for the ATS library, however, you may find the bundled source code informative.
