+
    +
  • 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
