Google Employee Breaks Pi World Record Day Before Pi Day

A Google employee has broken the world record for the most accurate value of Pi putting the number of digits at 31,415,926,535,897

A Google employee has broken the world record for the most accurate value of Pi putting the number of digits at 31,415,926,535,897

The new world record was announced today, March 14th-affectionately known as Pi Day-, which celebrates mathematics most well known constant, 3.1495...

Google revealed the news to coincide with Pi Day on March 14. Reading out the 31 trillion digits would take a person over 300,000 years, the report points out. A Yahoo engineer used the company's cloud tech in 2010 to calculate the 2 quadrillionth digit of pi, but did not calculate all the numbers in between. Yee also verified the calculation using Bellard's 7-term BBP formula. These were run in December and took 20 and 28 hours respectively.

"The biggest challenge with pi is that it requires a lot of storage and memory to calculate", Iwao says.

Iwao works as a developer and advocate for Google Cloud and used 25 Google Cloud virtual machines to complete her project. But Sze had not managed to calculate all the digits in between. She told CNN that it was her childhood dream to create such a record.

Halep responded after losing the opening set, dropping just three service points to level the match in fine fashion. Venus Williams reached the quarterfinals with a 6-4, 6-4 win over Mona Barthel.

The video lasts for 3 minutes and 14 seconds (notice the Pi theme), which is rather more than is required, and the closed captions can be very misleading. This is the first time the Pi calculation world record was ever broken in the cloud, and it breaks the most recent world record breakage, that of Peter Trueb in November of 2016. At this point I couldn't make out the "for what" bit of the sentence.

"There is no end with pi, I would love to try with more digits". "If a circle's diameter is 1, then its circumference is π". Earlier, Pi was calculated to 22 trillion points.

Pi has been computed to 31.4 trillion decimal places or 31,415,926,535,897 digits to be exact, using Google Compute Engine, powered by Google Cloud. Another part of the Cloud is the sharing and Google have published the computed disks in their entirety as disk sets- if you want to have a look yourself and check it's correct you can grab them here. Before cloud, the only feasible way to distribute such a large dataset was to ship physical hard drives. It's an irrational number that continues infinitely without repetition.
