FLINT: Fast Library for Number Theory

FLINT is a C library for doing number theory, maintained by William Hart. FLINT is licensed GPL v2+.

FLINT supports arithmetic with numbers, polynomials, power series and matrices over many base rings, including:

  • Multiprecision integers and rationals
  • Integers modulo n
  • p-adic numbers
  • Finite fields (prime and non-prime order)
  • Real and complex numbers (via the Arb extension library)

FLINT lib: how to delete a polynomial

In the library FLINT, we have the function fmpz_poly_clear to clear a fmpz_poly polynomial from the memory. But I am using the C++ interface of this library, so, my polynomials are of the type fmpz_polyxx or fmpz_mod_polyxx. I would like to know how…

Is it possible to handle fractions of multivariate rational polynomials using flint or bpas lib

I have to simplify such expressions: (1 + 2*a)/(b*(1 + c)) - 1/c, simplifying this expression i need to get something like this: (2*a*c - b*c - b + c) / (b*c*(c + 1)). I tried to use fmpz_mpoly_q from flint/calcium library and…
