%description
Giac is a Computer Algebra System made by Bernard Parisse. It  provides 
features from the C/C++ libraries PARI, NTL (arithmetic), GSL (numerics), 
GMP (big integers), MPFR (bigfloats) and also
  - Efficient algorithms for multivariate polynomial operations 
        (product, GCD, factorization, groebner bases),
  - Symbolic computations: solver, simplifications, limits/series, integration,
  - Linear algebra with numerical or symbolic coefficients.
  - Partial Maple and TI compatibility.
  - It has interfaces in texmacs and sagemath.

It consists of:
   - a C++ library (libgiac)
   - a command line interpreter (icas/giac)
   - an FLTK-based GUI (xcas) with interactive geometry and formal spreadsheets.

%description doc
The detailled html documentation and examples for giac and xcas. It is directly
accessible from xcas in many ways (browser, context search, thematic indexes).
It is strongly recommended for xcas usage. Note that the french part has been 
removed from the original source due to non free Licence.

%description xcas
Xcas is the Fltk graphic user interface to the computer algebra system giac. 
It supports formal computations, interactive 2D geometry, 3D plotting, 
spreadsheets with formal calculus and a Logo mode. There is also a programming 
editor, and many ways to consult the html help.
