%description
PARI is a widely used computer algebra system designed for fast computations in
number theory (factorizations, algebraic number theory, elliptic curves...),
but also contains a large number of other useful functions to compute with
mathematical entities such as matrices, polynomials, power series, algebraic
numbers, etc., and a lot of transcendental functions.

This package contains the shared libraries. The interactive
calculator PARI/GP is in package pari-gp.

PARI/GP is an advanced programmable calculator, which computes
symbolically as long as possible, numerically where needed, and
contains a wealth of number-theoretic functions.

# The final test is supposed to report "precision too low in forqfvec", but

# that architecture, just let it pass until somebody cares enough to diagnose
# the issue, or we stop building for 32-bit x86.
