  • Pi Day 2019 Google Employee Emma Haruka Creates New Guinness World Record Calculating Pi to 31 Trillion Digits

The calculations took around four months (121 days) to complete and computed digits are now the published by Google Cloud as disk snapshots, which are available to anyone.

A member of Google's staff has broken the world record for calculating Pi to the highest number of digits - at 31 trillion.

Google is celebrating Pi Day, the annual observation of the mathematical constant π, in a big way.

To calculate the number, Iwao used an application called y-cruncher on 25 Google Cloud virtual machines. As a child, she downloaded a program to calculate pi on her own computer.

Iwao did her number crunching primarily from Google's office in Osaka, Japan, where she works at as a developer and advocate for Google Cloud. She also credited Daisuke Takahashi, her former professor and a former world record holder for pi, for helping with the accomplishment. Pi is the ratio of the circumference of a circle to its diameter and it is represented by the three numbers of 3.14.

According to Google, Iwao has been fascinated by pi since she was 12.

Pi was first estimated thousands of years ago, and by the mid-20th century, mathematicians had calculated about 1,000 digits of the number, using a gear-driven calculator.

The pizza: For a lot of people, Pi Day is all about the related sales on pizza, and Thrillist has a list of the deals at chains and restaurants around the US.

Talking about her journey, she says, "When I was a kid, I didn't have access to supercomputers".

Typically, such calculations have been done on a single machine or "virtual machine" because of the difficulty for passing information back and forth over the network when using multiple machines working together.
