math/pari 2.17.2 OpenBSD

The PARI system is a package which is capable of doing formal computations on recursive types at high speed; it is primarily aimed at number theorists, but can be used by anybody whose primary need is speed.

It is possible to use PARI in two different ways:

1. as a library, which can be called from an upper-level language application (for instance written in C, C++, Pascal or Fortran);

2. as a sophisticated programmable calculator, named gp, which contains most of the control instructions of a standard language like C.
