Flint2

Flint2 provides a thin Haskell wrapper for Flint C-library.

Installation

• Install the C-library available from Flint. There are packages available for various operating systems.

• Install the Haskell interface with

cabal install Flint2

Quick Start

A simple program using the thin wrapper would be

import Data.Number.Flint

main = do 
  x <- newFmpz
  y <- newFmpz
  withFmpz x $ \x -> do
    withFmpz y $ \y -> do
      fmpz_set_ui x 7
      fmpz_set_ui y 6
      fmpz_mul x x y
      fmpz_print x  

which will print the numerical value 42.

In the app directory more practical information on how to use the thin wrapper can be found. The above example simplifies to

include Fmpz

main = do
  let x = 7 :: Fmpz 
      y = 6 :: Fmpz
  print $ x*y
  print $ factor (42 :: Fmpz)
  

which prints

42 
[(2,1),(3,1),(7,1)]
