PARIS (AFP) – A French software engineer said on Friday he was claiming a world record for calculating Pi, the constant that has fascinated mathematicians for millennia.
Fabrice Bellard told AFP he used an inexpensive desktop computer -- and not a supercomputer used in past records -- to calculate Pi to nearly 2.7 trillion decimal places.
That is around 123 billion digits more than the previous record set last August by Japanese professor Daisuke Takahashi, he said.
Takahashi, using a T2K Open Supercomputer, took 29 hours to crunch Pi to 2.577 billion digits.
Bellard took 131 days, comprising 103 for the computation in binary digits, 13 days for verification, 12 days to convert the binary digits to a base of 10 and three final days to check the conversion...
"It is a completely standard PC. The only unusual thing is that it has five 1.5-teraoctet hard disks. Mainstream PCs generally have only one 1-teraoctet disk."

New Record In Pi Eating Contest
Stories like this interest me not because of how many digits we can get to, but because of the creativity and work required to get those digits:
