DESCRIPTION

15       giac is an advanced symbolic and numeric calculator by Bernard Parisse.
16       The console interface is named icas or  equivalently  giac  The  corre‐
17       sponding GUI program is called xcas.  These programs has extensive html
18       documentation; One can also obtain some help about a keyword like this:

21          Returns the greatest common divisor  of  2  polynomials  of  several
22       variables
23          or of 2 integers or of 2 rationals.

26          gcd((x^2-1)*(y^2-1)*z^2,x^3*y^3*z+(-(y^3))*z+x^3*z-z)
