Just to "bring some balance to the thread"

:D

Actually, you can calculate Pi for yourself using the following formula:

Pi = 4 -4/3 +4/5 -4/7 +4/9 -4/11 ... Ad infinitum

Keep incrementing the denominator by 2 alternatively adding and subtracting the fraction.

(The previous post was tongue in cheek)

In Stephen Pile's "The Book of Heroic Failures", it was reported that the General Assembly of Indiana decided that the value of pi should be rounded up to 4.
It didn't work...

Thanks for that very helpful!  ;)

It takes a lot of iterations (about 1 million)  to get a significant number of decimal places, but you can produce a series up to say 1000. Take the average of the high and low pairs for the last 100, then take the average of the high and low pairs for the averages. Using that technique, you'll save computing time and get Pi to enough decimal places to see the six 9s in a row.

If you think that's awesome there is also Euler's identity:

e^iπ +1 =0

where

    e is Euler's number, the base of natural logarithms, and
    i is the imaginary number, which  is the square root of (−1)

did you see the 10yr old girl on Q&A who was able to recite pi to the 88th decimal place from memory ...   Tony Jones stopped her halfway through because he didn't have time to let her recite them all.

YYYAAAHHHHH Happy Pi day to all!
