There are only two hard things in computer science: cache invalidation, naming things, and offbyone errors
I am bonkers about permaculture

Mike Simmons wrote:Hmmm, really? For me it seems very much the other way around. Perhaps it's our respective backgrounds: I studied physics and engineering in school, and most of my early programming was to perform calculations for those disciplines. Whereas I see you're studying computer science. Perhaps the problems I was given were biased towards real numbers, while yours were biased towards integers?
Does discrete mathematics not include rational numbers? I don't remember ever being taught that 1/3 = 0 was an acceptable answer. Until computer programming, when I was taught that's simply what you get, regardless of whether it makes sense. But to the rest of the mathematicallyinclined world (as far as I know), 1/3 is a ratio, very much NOT equal to 0. And 0.3333333333 is not exactly equal to 1/3, but it's at least a fairly close approximation, much better than 0 or 1. How does 1/3 = 0 make sense in general? I would certainly agree that's it's what you want, sometimes. But I don't see how it makes more sense than 0.3333333333, as a default. And if the result must be an int, in general I am just as likely to want Math.floor() as Math.ceil() or Math.round(). (And yes, I know none of these exactly maps to integer conversion when both positive and negative values are considered, but I'm ignoring that extra messiness as beside the point.)
(And I feel much the same about numeric overflow being silently ignored when using ints. That's another discussion, but most of my arguments are the same in spirit, if not in detail.)
