There was a problem hiding this comment.
One problem that could arise is: (x/0>0) == (x/0<0) which seems a bit counter-intuitive.
There was a problem hiding this comment.
E.g., if we unnest some nested x/0>0 we get p <-> x/0>0 and then p -> x/0>0 and ~p -> x/0 <= 0. If we now evaluate this, we get p -> false and ~p -> false, which is inconsistent. Maybe this will give weird unexpected unsatisfiabilities in the future, where passing the IncompleteFunctionError may have been more useful.
