Quoting Scott Turner
This value, the computer's pi, differs from true pi by 0.000000000000000122...
Exercise for those doing numeric analysis 101: Explain why these two numbers are approximately the same. And if you found that one too easy, show how quickly following iteration converges to pi. iterate (\x -> x + sin x) 1 Cheers, Andrew Bromage
