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.

Emma Haruka Iwao, a cloud developer advocate for the company, smashed the previous record of 22 trillion, using 25 Google Cloud virtual machines.

Coming up with the figure used about 170TB of data and took 121 days to complete.

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

“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.”

Pi is the ratio of a circle’s circumference to its diameter, which begins with 3.14 and continues infinitely.

An application called y-cruncher was used to calculate pi, the same used by the previous record holders since 2010, but this is the first time that cloud computing was used.

“We use pi for everything in our daily life, designing buildings, building bridges, highways — pi is one of the most important constants in mathematics and science,” she continued.

The announcement comes on the annual Pi Day celebration, observed on 14 March.
