for that matter, slugging percentage, on base percentage etc etc. many baseball stats use 3 decimal places. baseball drew me into statistics when i was that age.
Don't use slugging percentage - it's not a percentage at all. Singles are 1, doubles are 2, triples are 3, and home runs are 4. It's a terribly named statistic that's on its own bizarre scale.
true, BUT... 3 digits are generally the norm and he original poster didn't specifically mention that he wanted percentages.
i would say slugging percentage is another good example because you can go into the ideas of how it is actually determined. the arbitrariness of it. leads into lots of other wonderful esoteric basbeball stats, vorp and all the rest.
