Yea interval arithmatic is what i thought was being talked about before. It's one of the things that lead me to seeing all kinds of issues trying to move forward with the language i made/mentioned in another comment. I decided that I needed to lift how I was handling numerics into multiple types: floats, rationals, intervals, etc. and design the whole thing so that you could have more than one kind of interval (i hadn't thought about doing it the way you describe), like open and closed around the upper and lower limits.
