It’s March 14th… known in scientific circles as “Pi Day”. Some math whizzes have suggested that Pi Day should really be called Pi Approximation Day. The ratio of a circle’s circumference to its diameter is commonly shortened to 3.14, but the sequence is actually infinite. Just in time for Pi Day on March 14 (or 3/14), a Google engineer has set a new record for the most Pi digits ever calculated.
The previous record for the known digits of Pi stood at 22.4 trillion digits. As Google announced on Pi Day 2019, Emma Haruka Iwao, a cloud developer advocate who’s been with the company for three years, has added 9 million digits to that figure.
Working out of a lab in Osaka, Japan, she used Google’s cloud-computing service to crunch 170 terabytes of data. For comparison, a single terabyte can hold 40 days worth of video. The process required 25 virtual machines running the y-cruncher program over four months.
According to Google, this marks the first time cloud computing has been used to calculate a record number of Pi digits.
