 computations in number theory (factorisations, algebraic number theory,
 elliptic curves...), but it 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.
 PARI is also available as a C library to allow for faster computations.")
