        "unit group"
        SYNTAX: X = unit()

        The current number field must be quadratic.
        
        The unit group of the current (quadratic) number field (see
        "? curnf") is displayed on the screen. In the imaginary
        quadratic case, the generator of the unit group is assigned to
        X; in the real quadratic case, the fundamental unit is assigned
        to X.
        

        Example 1: (correct)

                unit()


        Example 2: (incorrect)
