I did address it. Perhaps I should clarify. While it is a compromise in the IEEE 754 float standard to allow two infinities to compare equal, it is probably a better idea in a system that pretends to be mathematical rather than pragmatic and constrained, to reconsider what is most correct, and NOT allow inf-inf to become zero. Allowing comparison between infinities is hazardous. Taking a cue from the IEEE decision regarding floats and applying it to a more "symbolic" setup is questionable. As for the hazards of floating-point being well understood in the Sage community, I am surprised that anyone can speak for the community! Many people don't grasp the concept of binary representation and why it can't exactly handle 0.1 . And it gets worse from there.
