I was reading Petr Beckmann's book on the history of pi, which includes a chapter
on the digit hunters (people who calculated pi to large numbers of digits).
He says that (repeatedly) calculating pi to large numbers of places is a good way
of testing whether a machine is functioning accurately.

I just looked with google for such a program but couldn't find anything that went 
beyond the bit width (32 or 64) of the host machine. Does anyone know where
I can get the code? How do you do a calculation to 10^6 places on a 32 bit
machine?

Thanks Joe
