        "discriminant of a number field"
        SYNTAX: X = discnf()

        discnf computes the discriminant X of the current number field
        and displays its factorization on the screen.

        The factors and exponents are stored in AV (see "? avfunc"). 
        If the discriminant has its prime factorization 
        p1^e1 * ... * pN^eN in increasing order, then 
        AV[0]=p1, AV[1]=e1, ..., AV[2*N-2]=pN, AV[2*N-1]=eN.


        Example 1: (correct)

                discnf()


        Example 2: (incorrect)

                discnf(9)
