    Come now, no one rounds to 3! It's always either 3.14 or 3.141592.

    I've NEVER heard if anyone rounding to anything other than those two "versions" of pi, personally. Obviously for scientific purposes, you might want more digits. But dear god, 2.5 trillion "sig figs"? That's ridiculous. I can't imagine anything needing to be precise to 2.5 trillion digits...

    @TuxBobble: it's a question of scale. Most people choose not to attempt to comprehend what massively complex mathematical equations may benefit from such information.

    on the other hand, the mere thought that pi's decimal may repeat somewhere... in the seemingly infinite chaos of random numerals would be, to a mathematician and scientist, akin to irrefutably proving the existence of God.

    someone explain to me without being a douche, why the hell they cant just keep projecting the equation forever and forever... is it possible to figure out some code that keeps going with the string of numbers? making anything like this kinda blaze? if it is a infinite string of numbers, how come we cant just have it constantly evolving and never ending?

    is this naive of me to ask?

    @AstroWolf: because, those numbers take up space, and as it stands they take up a whopping 25 terabytes. They could have easily kept going and going and going but it really wouldnt ahve been worth it in terms of system resource use. I would imagine they would use something much more speedy than a harddrive because of I/O needs which would have cost mucho $$$$

    I mean sure we could do it, but im sure this computer is going on to do much more important things where such precision in pi isnt needed.

    @AstroWolf: I would say, that as computers get faster and faster, it actually becomes more cost effective to start over with a new supercomputer than to keep it going on an old system. Imagine if we were still using punch-cards to calculate pi. Now imagine how much faster an x86 processor can do it.

    Then imagine several x86's linked together.

    Then several multi-core processors.

    Then a supercomputer with hundreds of cores

    then thousands

    then tens of thousands.

    It's like the pink dragon. You keep chasing it. But you never CATCH the dragon!

    @srw: The sasquatch, while non-infectious (and probably not infectable), isn't a major factor due to their small number and highly isolated habitat.
