Really, I'm curious, is there any real-world problem where anyone
would actually *need* pi to a G decimal places? I mean, are these kind
of computations actually useful for someone, or is it just a matter of
"we have the power to do it, so let's do it" thing? Other than entry
into the Guinness book of records, that is?

Or maybe there are still people who believe pi is rational rather than
transcendent, and look for a cyclic repeat pattern in the decimals?
