A French computer scientist says he calculated PI to a new record of digits on a desktop PC. Fabrice Bellard calculated PI to nearly 2.7 trillion digits, which is about 123 billion more than the previous record.
The big news here is that he used a desktop PC and the previous record was set on a Super Computer. The calculation took 131 days and fills a TB of HDD space.
Apparently the trick is in the algorithm he used to achieve this new record on inferior hardware.
