FLINT (Fast Library for Number Theory)

Mailing list: https://groups.google.com/g/flint-devel

Overview

FLINT is a C library in support of computations in number theory. It's also a research project into algorithms in number theory. FLINT consists mainly of fast scalar and polynomial arithmetic, factorization and linear algebra over many basic rings (integers, rationals, reals, finite fields, number fields, p-adics). It includes some higher-level functionality for algebraic and analytic number theory.

FLINT 2, released in 2011 was a complete rewrite of FLINT 1.x from scratch. FLINT 3, released in 2023, incorporates the Arb, Antic, Calcium and Generic-Rings libraries, formerly developed separately.

Building from source

This example assumes that GMP, MPFR and the GNU build system are already installed. To install them on a Ubuntu system, write

apt install libgmp-dev libmpfr-dev make autoconf libtool-bin

possibly with super-user privileges.

To download, bootstrap, configure and build everything, write

git clone https://github.com/flintlib/flint.git && cd flint
./bootstrap.sh
./configure                        # ./configure --help for more options
make
make check                         # optional
make install                       # optional
make examples                      # optional
cd doc && make html && cd ..       # optional: documentation

See FLINT's documentation for further instructions on how to build FLINT.

Authors

FLINT was started in 2007 by David Harvey and William Hart. Maintenance was later taken over solely by William Hart who remained in charge of the project until 2022. A large number of authors have contributed to FLINT over the years; for a complete list, see https://flintlib.org/authors.html or the AUTHORS file.

The current maintainers are:
