Re: [math-fun] why can a line of slope 10^n determine n decimal digits of π?

Gary, it doesn't. I'm not sure what led you to think that the numbers are 31, 314, etc., but rather the actual numbers are only approximations to these integers. --Dan << Thanks, Joshua. But I still don't get it. Why does a line of slope -10 carve out exactly 31 arcs and not, say, 30?
