Just in time for Pi Day , a new world record has been set for calculating the ratio of a circle's circumference to its diameter. On Thursday, Google revealed developer advocate Emma Haruka Iwao, with the help of the tech giant's cloud platform, calculated Pi to 31 . 4 trillion decimal places

Google said it calculated Pi to 31 ,415,926,535,897 decimal places--setting a new Guiness World Record in the process. Of course, this has to do with computations resulting in 31 . 4 trillion digits. Most people aren't going to expect their SSDs to Google won't end its Pi celebrations end on Pi Day .

A new world record has been set for calculating the ratio of a circle's circumference to its diameter.

On Thursday, Google revealed developer advocate Emma Haruka Iwao, with the help of the tech giant's cloud platform, calculated Pi to 31.4 trillion decimal places, beating the previous record by nearly 9 trillion digits.

To do this, Iwao's team used a program called ycruncher capable of computing Pi to trillions of digits powered by 25 virtual machines run through Google Cloud's Compute Engine.

Google SMASHES world record on ' Pi Day ': First 31 . 4 trillion digits of the mathematical constant are calculated - but the task took 121 days and 2,795 hours of computer power to complete. A Google employee has broken the world record for calculating Pi to the highest number of digits - at 31 trillion .

Iwao and a Google team computed pi to 31 . 4 trillion decimal places or pi multiplied by 10 to the 13th power, ousting the previous record set in 2016 of 22. 4 trillion digits. Iwao's effort marked another first by relying on cloud technology, which had never been used for such a massive pi calculation .

"The biggest challenge with pi is that it requires a lot of storage and memory to calculate," said Iwao, who has worked with the company for nearly four years, in a blog posted published Thursday by Google.

The calculation required 170 terabytes of data, about the same amount of data as the entire Library of Congress print collection, said Google.

After about 4 months of calculating, Iwao arrived at the record-breaking result.

"The world of math and sciences is full of records just waiting to be broken," wrote Iwao in a separate Google post. "We had a great time calculating 31.4 trillion π digits, and look forward to sinking our teeth into other great challenges."

Google fined €1.49bn for restricting rivals' ads.
Google has been fined €1.49bn (£1.28bn) by the EU for breaching competition laws with its AdSense advertising service - its third such fine in as many years. Announcing the new fine, the EU's competition commissioner Margrethe Vestager said Google had restricted rivals from appearing in online search advertisements. Ms Vestager said the company had been fined for its "illegal practices in search advertising brokering to cement its dominant market position". "They shouldn't do that - it denied consumers choice, innovative products and fair prices," added Ms Vestager.
