Emma Haruka beats world record for most-calculated digits of pi

The Googler beat the Guinness World Record with a value of 31,415,926,535,897 digits for pi.

Google Cloud Developer Advocate Emma Haruka Iwao has been using Google Compute Engine, powered by Google Cloud, to calculate the most accurate value of pi. Today, on Pi Day, she beat the Guinness World Record of most-calculated digits of pi with 31,415,926,535,897 digits. 

When you divide a circle’s circumference by its diameter, you get Pi, which is known as its first three digits, 3.14, because the number is infinitely long. 

Extending the known sequence of digits in pi is especially hard as it follows no set pattern. Emma used the power of the cloud for the task, making this the first time the cloud has been used for a pi calculation of this magnitude.

Pi is commonly used in engineering, physics, supercomputing and space exploration. The value can be used in calculations for waves, circles and cylinders.

Emma says there are a lot of mathematical problems out there to solve, and “we’re just at the beginning of exploring how cloud computing can play a role".

She said: 

“When I was a kid, I didn’t have access to supercomputers. But even if you don’t work for Google, you can apply for various scholarships and programs to access computing resources. I was very fortunate that there were Japanese world record holders that I could relate to. 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.”

At Google, Emma focuses on high-performance computing and programming language communities. Her job is to work directly with developers, helping them to do more with the cloud and share information about how products work.
