PARI/GP computer algebra system

PARI/GP is an open-source computer algebra system developed at the University of Bordeaux since the early eighties. It is designed for fast computations in number theory, algebraic number theory, elliptic curves, modular forms, and L functions. The system offers a wide range of functions to work with mathematical entities like matrices, polynomials, and algebraic numbers, as well as transcendental functions, numerical summation, and integration routines. PARI is available as a C library for quicker computations. The system includes an interactive shell called gp and a scripting language named GP. Additionally, gp2c is a GP-to-C compiler that can enhance script performance significantly. Recent updates include the release of PARI-2.15.5 and PARI-2.16.1 (alpha). PARI/GP was honored with the 2021 Richard D. Jenks Memorial Prize for Excellence in Software Engineering Applied to Computer Algebra. Moreover, a new book titled "Numerical Algorithms for Number Theory using PARI/GP" has been published. The system continues to evolve with regular workshops and updates to enhance its functionality and performance.
