It took 121 days for Google's virtual machines to reach the magic number.

Her milestone is certified by Guinness World Records, making Iwao the third woman to set a world record for determining the number that continues infinitely without repetition. Google announced her accomplishment on March 14, which just so happens to be pi day.

A Google employee smashed a Guinness World Record by calculating the value of pi to more than 31.4 trillion digits. Her calculation required, says Google in their blog on her achievement.

Running the calculation on the cloud gives the mathematically curious a major upgrade in convenience, Google said.

This feat was achieved by Emma Haruka Iwao, a Cloud Developer Advocate at Google.

Here's the full mind-boggling number: 31,415,926,535,897 digits. "If you were paying attention in grade school, you'll remember pi is the number that describes how the circumference of a circle relates to its diameter (how wide a circle is if you draw a line straight across the middle)", writes Brian Resnick. "There is no end with pi", Iwao tells the BBC.

The contstant is used in engineering, physics, supercomputing and space exploration - because its value can be used in calculations for waves and circles.

Googler Emma Haraku Iwao took her fascination with pi all the way to 31.4 trillion digits. It's the ideal reading material for Pi Day. When I was a kid, I downloaded a program to calculate pi on my computer, ' Emma said.

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. "At the time, the world record holders were Yasumasa Kanada and Daisuke Takahashi, who are Japanese, so it was really relatable for me growing up in Japan".
