My point about the complex roots of X^2 + 1 being indistinguishable was not to say that in any sense they are equal*. Just that there is no way of specifying one rather than the other. --Dan __________________________________________________ * This might be a feasible approach, but it would, I agree, sure make a mess of the complex plane.
