pari-extra binary package in Ubuntu Precise i386

 PARI/GP 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.
 PARI is also available as a C library to allow for faster computations.
 .
 Originally developed by Henri Cohen and his co-workers (University Bordeaux I,
 France), PARI is now under the GPL and maintained by Karim Belabas with the
 help of many volunteer contributors.
 .
 This is a dummy package which depends on
  pari-galdata: the Galois resolvants for the polgalois function.
  pari-elldata: the elliptic curves database for the ellsearch function.
  pari-seadata: the modular polynomials for the ellap function.
 It can be safely removed after the upgrade.
