Enthusiasts calculate value of `pi` to more than 10 trillion digits

A computer scientist based in US and a systems engineer in Japan have together calculated the value of mathematical constant ‘pi’ up to a little more than 10 trillion digits.

The enthusiasts faced several impediments in their path like hard drive failures, computer heating the air in its room to nearly 40 °C and so on and narrowly managed to escape the widespread technical disruptions caused by the Japan earthquake.

Despite all the odds, they still emerged successful in their quest to smash their previous Guinness World record and set a new one.

Alexander Yee and Shigeru Kondo had previously calculated values upto 5 trillion digits, New Scientist reported.

‘Pi’ is actually the ratio between the circle’s circumference and its diameter.

Both the enthusiasts started computing the value from October 16, 2010 but unfortunately had to start all over again when their hard disk crashed on December 9.

However they managed to accomplish what they intended to on August 26 after which they had to verify if all the 10 trillion digits computed were correct, the last digit of which is 5.
