Google Cloud Calculates Pi To 100 Trillion Digits

Google Cloud Calculates Pi To 100 Trillion Digits

"Google Cloud developer advocate Emma Haruka Iwao and her colleagues say they've calculated Pi to 100 trillion digital decimal places." 
"Iwao and her team previously set the record in 2019 when they carried out a calculation to an accuracy of 31.4 trillion digits." 
"In 2019, the calculation (which figured out a third as many digits as the most recent attempt) took 121 days. This time around, the calculation ran for 157 days, 23 hours, 31 minutes and 7.651 seconds, meaning the computers were running more than twice as quickly despite Iwao using "the same tools and techniques." Around 82,000 terabytes of data were processed overall. Iwao also notes that reading all 100 trillion digits out loud at a rate of one per second would take more than 3.1 million years. And in case you're wondering, the 100-trillionth decimal place of Pi is 0."
