Today is Pi Day, and this year we know nine trillion more digits of the celebrated never-ending number than we did the last time Pi Day came around, thanks to a record-breaking calculation by Google engineer Emma Haruka Iwao.
Emma spent four months working on the project in which she calculated pi to 31.4 trillion digits. Google announced her accomplishment on March 14, which just so happens to be pi day.
Google had the craziest way to celebrate Pi Day by making the most accurate Pi calculation till date.
Calculating it is a common task for supercomputers, and developer advocate Iwao used Google Cloud to calculate it to 31,415,926,535,897 digits. The world record holders at the time were two Japanese citizens.

VAR made its World Cup debut at the men's tournament in Russian Federation past year . The announcement comes in the face of considerable opposition from European clubs.
Cloud computing services store and manage customers' software and data online. And as a result, Google has broken a GUINNESS WORLD RECORDS title. In addition, with the help of 25 virtual machines, complete calculation can be done in 121 days. The first digits, 3.14, are well known but the number is infinitely long. As you would expect that amount of digits requires a lot of storage - she calculates she required 170 terabytes to finish the calculation. But even if you don't work for Google, you can apply for various scholarships and programs to access computing resources.
Pi Day, also known as Pie Approximation Day, is held every year on March 14 in honour of the mathematical constant Pi. And one woman is taking the celebration farther than it's ever gone before.
The contstant is used in engineering, physics, supercomputing and space exploration - because its value can be used in calculations for waves and circles.
Mathematicians have been able to calculate 40 digits of pi since the 1700s.
