On August 2, 2010, We have successfully completed the computation of Pi to 5,000,000,000,000 decimal places on a single desktop computer in record time.

This is 2.3 trillion digits more than the previous world record by Fabrice Bellard (December 2009). Therefore, we are declaring 5 trillion digits as the new world record. It was done using a program created by Alexander Yee and a desktop computer built by Shigeru Kondo.

If the digits were stored in an uncompressed ascii text file, the combined size of the decimal and hexadecimal digits would be 8.32 TB.

y-cruncher is a powerful multi-threaded program/benchmark that is becoming an increasingly popular tool within the computer enthusiast community. It was also used for the current world record for most digits computed for several other famous constants. (These include: e, Square Root of 2, Golden Ratio, Euler-Mascheroni Constant, Natural Log of 2, Apery's Constant, and Catalan's Constant.)

This program implements the digit-extraction algorithm for Pi using the BBP formulas. It's sole purpose was to verify the main computation.
