Description:

NTL is a high-performance, portable C++ library providing data structures
and algorithms for arbitrary length integers; for vectors, matrices, and
polynomials over the integers and over finite fields; and for arbitrary
precision floating point arithmetic.

NTL provides high quality implementations of state-of-the-art algorithms for:
* arbitrary length integer arithmetic and arbitrary precision floating point
arithmetic;
* polynomial arithmetic over the integers and finite fields including basic
arithmetic, polynomial factorization, irreducibility testing, computation
of minimal polynomials, traces, norms, and more;
* lattice basis reduction, including very robust and fast implementations of
Schnorr-Euchner, block Korkin-Zolotarev reduction, and the new
Schnorr-Horner pruning heuristic for block Korkin-Zolotarev;
* basic linear algebra over the integers, finite fields, and arbitrary
precision floating point numbers.
