computer algebra system
Xcas Pad is a computer algebra system.
As maths kernel, Xcas Pad embed a port of the Giac/Xcas library.
Giac/Xcas library is a powerful maths kernel used by many platforms.
Despite Xcas Pad is released here, still is conceptual and it means to many things could be changed and is in continuous development, so keep in mind the future releases could have new and better features.
Thanks to Bernard Parisse for write and share the Giac library.
