Records are made to be broken. In March 2022, we calculated 100 trillion digits of pi using Compute Engine. This is the second time we’ve used Google Cloud to calculate a record number of digits for the mathematical constant, tripling the number of digits in just three years after our world record with 31.4 trillion digits in 2019.

Check out the official blog for more details about the technical details and architecture of the calculation. And for more on the history of calculating pi, check out this post on The Keyword.

We’ve updated the API to serve all of the 100 trillion digits of pi. We’ve also published the entire results on Cloud Storage so you can download the files (caution: they are really big). //

Listen (Piano Genie)

What does Pi sound like? Each Pi digit is converted to a musical note so you can get to know Pi via music!

Piano Genie is an neural network model that allows you to play a note from 1 to 8, and intelligently map it to a great sounding piano performance. In this demo, we use each digit for [0, 7] and reuse the last digit for [8, 9], and use Piano Genie to map to the next logical note for great sounding Pi.

With 100 trillion digits and playing at 314 BPM, it'll play for 605 516 years!
