You might be interested in the book, A History of Pi, by Peter Beckmann.

Millions of digits of pi have now been computed. My Handbook of Mathematics Functions gives 25 digits as 3.1415 92653 58979 32384 62643. There is an interesting history of fractions that approximate pi. Older texts always included 22/7 (correct to 3 decimal places, rounded) and I believe that ancient China is credited with 355/113 (6 decimal places). With computer help we have discovered 104348/33215 (at least as good as a ten digit calculator).
