pari: pari (a computer algebra system) pari: pari: PARI/GP is a widely used computer algebra system designed for fast pari: computations in number theory (factorizations, algebraic number pari: theory, elliptic curves, modular forms, L functions...), but also pari: contains a large number of other useful functions to compute with pari: mathematical entities such as matrices, polynomials, power series, pari: algebraic numbers etc., and a lot of transcendental functions. pari: pari: Homepage: https://pari.math.u-bordeaux.fr/ pari:
