Readme for fast-arithmetic-0.3.2.5
[back to package description]fast-arithmetic
This is a library for fast arithmetical functions using ATS, with a Haskell wrapper.
It is intended to supplement (but not replace) arithmoi and combinat where speed is important. In particular, this library provides a fast primality check and fast computation of basic combinatorial functions.

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 atspkg, and build with
$ atspkg build
Documentation
You can find documentation for the Haskell library on Hackage. Unfortunately, there is no documentation for the ATS library, however, the bundled source code is commented.
