Tokyo - A team of researchers at a leading national university have set a world record by calculating the value of pi to 1,2411 trillion places, one of the researchers said on Friday.
Pi is a the mathematical ratio used to measure the area of circles and its decimal points are infinite.
Professor Yasumasa Kanada and nine other researchers at the Information Technology Centre at Tokyo University calculated the value for pi, with a Hitachi supercomputer, for 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 recognised by Guiness World Records - 206 158 billion places - which Kanada also helped calculate in 1999.

Kanada's team spent five years designing the programme used to calculate pi in the September experiment to test the efficiency of the supercomputer, Kudo said.
The Hitachi supercomputer is capable of two trillion calculations per second, or twice as fast as the one used for the current Guiness record calculation. - Sapa-AP
