Pi world record calculation broken by Google employee Emma Haruka Iwao

Emma Haruka Iwao and a Google team computed Pi to 31.4 trillion decimal places or Pi multiplied by 10 to the 13th power

Iwao's calculation took 121 days to finish and needed 25 virtual machines.

The feat was achieved using a Google Compute Engine virtual machine cluster to run the Pi benchmark program y-cruncher.

"The biggest challenge with pi is that it requires a lot of storage and memory to calculate", says Iwao, whose calculation required 170 terabytes of data to complete, about the same amount of data as the Library of Congress' print collections hold.

Iwao emphasized the importance of cloud computing, and how it can be used to solve complicated mathematical constants, such as pi.

"It was my childhood dream, a longtime dream, to break the world record for pi", the Osaka, Japan-based developer and Google Cloud advocate tells CNN Business.

These are the last 97 digits of the 31,415,926,535,897 now calculated for pi.

A queer software engineer at Google has calculated the length of the number pi to a new world record.

Pi is the ratio of the circumference of a circle to its diameter.

Emma Haruka Iwao grew up fascinated by pi. It is significantly used in geometrical calculations. 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.

Google announced her achievement Thursday - but Iwao has been striving toward this moment since she was 12 years old. Saying the value of an irrational and transcendental number is quite a popular thing to do on Pi Day.

Talking about her journey, she says, "When I was a kid, I didn't have access to supercomputers".

'I was very fortunate that there were Japanese world record holders that I could relate to myself.

"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.
