>I once knew it better too, but it's seldom used in statistics...I believe they've calculated it's value to something like 500,000 places now, they use it to test new super Crays and the like, apparently...that kind of precision isn't needed too often :)

I once read a fascinating article (New Yorker mag, I think) about a couple of brothers who had build a computer to calculate Pi in their apartment. They held the world record at the time of the article.
