So when one says "from a to b", does that mean the interval [a,b], or (a,b), or [a,b) or (a,b] ? I know that I use "thru" in place of "to" if I want to unambiguously indicate "]". I think I use "from" to mean "[", but I won't swear to not ever using it for "(". And then there's the phrase "between a and b". If you're going to invent new words (and I'm pretty sure I'd rather stick with "nonnegative") they really ought to be clearly better than the alternative. I understand the awkwardness of phrases like "greater than or equal to", but it's only a problem when speaking. Otherwise, I can write ">=", or, in my favorite programming language, "ge". --ms John McCarthy wrote:
We could pretend the Russians invented it and use otzero, meaning the same as fromzero but shorter.
