Google developer calculates pi to 100 trillion digits

Emma Haruka Iwao, a Google Cloud developer advocate, has calculated more pi trillion digits than she did three years ago, breaking her own record. After figuring out pi to its 31.4 trillionth digit is 2019. Iwao was able to do it again in 2019 using the same Google Cloud y-cruncher program. But this time he got a result of zero.

In March 2022, computers finish what began in October 2021. In 2018, it took more than twice as long as it did in 2019 to come up with a smaller number. Iwao says that she used the same tools and methods. The higher speed is due to how Google Cloud has changed since then. This includes 100Gbps networking, balanced Persistent Disks, and other things that we’ve talked about in this deep dive into the calculations.

To put it another way, it takes a lot of data processing to figure out numbers this far away. The blog post says that computers processed about 19,000 terabytes of data during the first attempt at the record-breaking calculation. For the computer to figure out the 100 trillionth digit, it had to use 82,000 terabytes of data.

In addition to giving some fun facts. The blog post showed how big the number 100 trillion is in terms of people. A Google developer or a new study in Nature says that 100 trillion pie digits crust inches would reach from Earth to the moon and back 3,304 times. If you want to see the source code for all 100 trillion digits, you can find it here.

Despite faster computers, the announcement comes after Pi Day 2022. But it’s just in time for Tau Day. Which is on the 28th of this month and celebrates a different circle constant whose name doesn’t rhyme with “pie.”
