[![Latest release](http://img.shields.io/bower/v/purescript-bigints.svg)](https://github.com/sharkdp/purescript-bigints/releases)

[![Build Status](https://github.com/sharkdp/purescript-bigints/workflows/CI/badge.svg?branch=master)](https://github.com/sharkdp/purescript-bigints/actions?query=workflow%3ACI+branch%3Amaster)

**Note**: This package is deprecated. You probably want to use [`purescript-js-bigints`](https://github.com/purescript-contrib/purescript-js-bigints) instead.

A library for calculations with arbitrary length integers.

This is a simple wrapper around [BigInteger.js](https://github.com/peterolson/BigInteger.js)

by [Peter Olson](https://github.com/peterolson).

## Module documentation

- [Published on Pursuit](http://pursuit.purescript.org/packages/purescript-bigints/)

## Example

```purescript

x = fromInt 42

y = (fromJust <<< fromBase 16) "fe45aab12"

mersenne10 = (fromInt 2) `pow` (fromInt 89) - one

> x `pow` x

fromString "150130937545296572356771972164254457814047970568738777235893533016064"

> toNumber (y * mersenne10)

4.2248205181941055e+37

> prime mersenne10

true

```

## Installation and usage

You can install this package via Bower. You will also need [BigInteger.js](https://github.com/peterolson/BigInteger.js), which can be installed via `npm`:

```

bower install purescript-bigints

npm install big-integer

```

For the browser, remember to bundle `BigInteger.min.js` with your code.

## Development

```

bower install

npm install

```

Then, use `pulp` to build, run tests and generate the documentation.
