I did not suggest that midpoint([1,+oo]) should be REALMAX at Level 2 !

All what I said is that in my opinion the midpoint of unbounded
intervals can be undefined at Level 1, while can be defined at Level 2
after discussion. These discussions could lead us deciding that at
Level 2 midpoint([1,+oo]) = REALMAX, or anything else including NaN as
suggested by Arnold. I don't wish to express any personal suggestion
of what could be the midpoint of unbounded intervals at Level 2 now,
since it is not the topic of the current discussion.
