Definition talk:Ceiling Function

I added this and the floor function to the number theory symbols page. Feel free to move them if that does not seem like an appropriate location. --cynic 03:32, 18 October 2008 (UTC)

Good question. The only extensive use I've seen of these is in the loose field of study usually referred to as "discrete mathematics" which takes on board aspects of analysis, number theory, calculus and what-all to investigate the issues behind, for example, the expression of results using implied infinities / infinitesimals etc. in a non-infinite context (for example, in a computer). Numerical analysis is I believe a sub-field of this. Whether to include a separate category for this I'm not sure - the best way of defining "discrete mathematics" is calling it "what Knuth does" but then he tends to refer to it as "concrete mathematics". Colourful guy. --Matt Westwood 09:44, 18 October 2008 (UTC)
