Pi Day: Google calculates most accurate value of Pi

Company employee Emma Haruka Iwao, here, used an application called y-cruncher on 25 Google Cloud virtual machines. It is defined as the ratio of a circumference of a circle to its diameter. It is significantly used in geometrical calculations.

Google cloud developer advocate Emma Haruka Iwao thinks in terms of trillions of pi digits. Google and Yee broke Trueb's record by almost 9 trillion digits.

For her experiment, Iwao relied on y-cruncher, a free app originally developed by Alexander Yee to turn Pi calculations into a benchmarking and stress-test tool for overclocking enthusiasts - which has been used in previous world records.

Why it matters: This is the first time the Pi record has been set using a commercial cloud service and the first achieved using solid state drives. It took 121 days for Google's virtual machines to reach the magic number. During the entire time it took for calculations, the Google Cloud server were kept switched on to avoid any interruptions.

Iwao has been interested in the famous irrational number from an early age.

The world record for manually calculating pi is held by British mathematician William Shanks, who managed 527 digits without a computer.

"Pi seems simple - it starts with 3.14", she says. The interesting thing about Pi is that it's value is infinite in length. The previous world record was 22.4 trillion digits and it was achieved back in November, 2016 by Peter Trueb.

'I was very fortunate that there were Japanese world record holders that I could relate to myself.

'When I was a kid, I didn't have access to supercomputers But even if you don't work for Google, you can apply for various scholarships and programs to access computing resources. I would list it here but I suspect that many digits may break the website.
