1.24 trillion places this was an AOL special on Dec 7,2002: TOKYO (Dec. 6) - A team of researchers at a leading national university have set a world record by calculating the value of pi to 1.24 trillion places, one of the researchers said Friday. Professor Yasumasa Kanada and nine other researchers at the Information Technology Center at Tokyo University calculated the value for pi with a Hitachi supercomputer over 400 hours in September, project team member Makoto Kudo said. The new calculation is more than six times the number of places in the record currently recognized by Guinness World Records - 206.158 billion places - which Kanada also helped calculate in 1999. ''We would need to verify it, but it sounds like Professor Kanada has broken his own record,'' Guinness World Records spokesman Neil Hayes said. He said a Guinness math expert would need to verify the data. Kanada's team spent five years designing the program used in the September experiment, Kudo said. The Hitachi supercomputer is capable of 2 trillion calculations per second, or twice as fast as the one used for the current Guinness record calculation. Pi, usually given as 3.14, is the ratio of the circumference to the diameter of a circle and has an infinite number of decimal places. Such an extremely precise calculation of the figure isn't necessary for any practical scientific use, but researchers say it contributes to improving scientific calculation methods. 12/06/02 10:42 EST Copyright 2002 The Associated Press.

Yep. 1.24 trillion is a mighty huge number. But get this... In 1700: Dutch schoolmaster takes lifetime just to memorize 800 digits of PI. In 2009: Normal computer takes a few seconds to do it and check his readings May 15 09, 5:52 AM

How many places has pi been calculated to? What is the highest number that pi has been recorded down to? What is the farthest digit of pi that has been recited? (Ex. The hundredth...) How is it possible to determine the area of a circle, if Pi has been calculated to 1.24 trillion places (and counting) - surely the calculated area of the circle grows (albeit infinitesimally) every time the calculation of Pi is extended?
