Fittingly, she used 25 Google Cloud virtual machines to generate the enormously long number.
It's Pi Day, the 3/14 celebration of perhaps the most famous number in history.
Iwao, who performed the calculation from Google's office in Osaka, Japan, said it was the first time a pi record was calculated using cloud technology. During the entire time it took for calculations, the Google Cloud server were kept switched on to avoid any interruptions.
On her Tiwtter, Iwao describes herself as: "Neutral Good with Lawful Evil traits / Developer Advocate for Google Cloud Platform / Software engineer, gamer, queer, and feminist".
Emma spent four months working on the project in which she calculated pi to 31.4 trillion digits.
Pi is the ratio of a circle's circumference to its diameter.
"We achieved this feat using y-cruncher, a Pi-benchmark program developed by Alexander J. Yee, using a Google Compute Engine virtual machine cluster", the post reads. She told CNN that it was her childhood dream to create such a record. It is significantly used in geometrical calculations. The computations, which rely on super computers to crunch trillions of numbers, have fueled an escalating scientific competition, but most real-world applications of Pi require only several hundred digits.
Even with Google's infrastructure on her side, determining trillions of digits was no simple task.
She said she had been using computer programs to calculate pi since she was 12 years old.
Pi is an infinite number essential to engineering. It's the flawless reading material for Pi Day.
Emma said: "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.
