Iwao set the newest Guinness World Record for the most accurate value of pi on Thursday.
The announcement comes on the annual Pi Day celebration, observed on 14 March.
In honor of Pi Day on Thursday, March 14, Google announced that the company's own Emma Haruka Iwao has surpassed the world record pi computation by almost nine trillion digits. "And I learned some people use computers to calculate millions and billions of digits of pi". But since it's an irrational number, "there's no end to how many of its digits can be calculated". In a blog post, Emma said that they managed to successfully compute the Pi value to 31.4 trillion decimal places or 31,415,926,535,897.
Iwao did her number crunching primarily from Google's office in Osaka, Japan, where she works at as a developer and advocate for Google Cloud.
Ms Iwao said she had been fascinated by the number since she had been a child.
In mathematics pi is the ratio of a circle's radius to its circumference, has far more digits that continue infinitely without repetition. 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.
This year marks the 31st anniversary of Pi Day, which is believed to be celebrated first by physicist Larry Shawand and his peers at the Exploratorium in San Francisco in 1988.
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.
