pari
[Batut et al.]
is developed at Bordeaux University, and
distributed as a free software. Though it has a certain facility to computer
algebra, its major target is the operation of numbers (bignum,
bigfloat) related to the number theory. It facilitates various
function evaluations as well as arithmetic operations at a remarkable
speed. It can also be used from other external programs as a library.
It provides a language interface named `gp' to its library, which
enables a user to use PARI as a calculator which runs on UNIX.
The current version is 2.0.17beta. It can be obtained by several ftp
sites. (For example, ftp://megrez.ceremab.u-bordeaux.fr/pub/pari
.)
