Of course everybody knows that pi is approximately

Slightly off-topic, I once wrote a short Perl program to calculate pi on my
9600. It was great, but went through an absurdly large number of
calculations (multiple millions, I think) to accurately determine an
absurdly small number of places (15, I think). Makes you wonder how people
used to do it by hand, and why. I notice on the web that there's now a
formula for calculating the nth arbitrary digit of pi, in hexadecimal
anyway; I haven't yet researched to find out whether there's a binary
solution.
