She said the calculation took about 121 days to complete - with zero breaks, otherwise it would have been disrupted.

The 31.4 trillion digits have been recognized by the Guinness Book of World Records as the most accurate value of pi after breezing past the record of 22.4 trillion digits set by Peter Tueb in November 2016.

Google is celebrating Pi Day, the annual observation of the mathematical constant π, in a big way. What's even interesting is that Google used cloud to make the Pi calculation.

Calculating it is a common task for supercomputers, and developer advocate Iwao used Google Cloud to calculate it to 31,415,926,535,897 digits. But since it's an irrational number, "there's no end to how many of its digits can be calculated". 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.

MPs vote in favour of postponing Brexit with the European Union approval
And fourth , they will vote on a bid by Labour MP Chris Bryant to BLOCK Theresa May from holding a third vote on her Brexit deal. MPs have voted against holding a second Brexit referendum this evening by a substantial majority of 249 votes.

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's almost nine trillion digits more than the previous world record set by Peter Trueb in November 2016.

According to Google, Iwao has been fascinated by pi since she was 12. When I was a kid, I downloaded a program to calculate pi on my computer, ' Emma said.

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.

When I think of pi, I think of three digits: 3.14.

"I'm really happy to be one of the few women in computer science holding the record, and I hope I can show more people who want to work in the industry what's possible", she said. The semi-official holiday for the unique number is celebrated by eating actual pies.
