        "multiplicative m-adic value"
        SYNTAX: X = mval(m, A)

        m is an expression whose value is a positive integer, and A is
        an expression whose value is a nonzero element of Z or Q.

        X is assigned the multiplicative m-adic value of A, i.e.
        X equals m^(-aval(m,A)) (see "? aval").
