It was used in the world record calculations of 2.7 trillion digits of π in December 2009, [3] 10 trillion digits in October 2011, [4] [5] 22.4 trillion digits in November 2016, [6] 31.4 trillion digits in September 2018–January 2019, [7] 50 trillion digits on January 29, 2020, [8] 62.8 trillion digits on August 14, 2021, [9] 100 trillion ...
Calculated pi to 72 digits, but not all were correct 71: ... 105 days 22,459,157,718,361 = ... Google's web service making all 100 trillion digits available
Emma Haruka Iwao (born April 21, 1984) is a Japanese computer scientist and cloud developer advocate at Google. [5] [6] In 2019 Haruka Iwao calculated the then world record for most accurate value of pi (π); which included 31.4 trillion digits, exceeding the previous record of 22 trillion.
The digits of pi extend into infinity, and pi is itself an irrational number, meaning it can’t be truly represented by an integer fraction (the one we often learn in school, 22/7, is not very ...
A team from the University of Applied Sciences Graubünden in Switzerland claims it has calculated for 62.8 trillion digits of Pi.
The computation took (with three interruptions) 105 days to complete, [48] the limitation of further expansion being primarily storage space. [47] In March 2019, Emma Haruka Iwao, an employee at Google, computed 31.4 (approximately 10 π) trillion digits of pi using y-cruncher and Google Cloud machines. This took 121 days to complete. [50]
Later computers calculated pi to extraordinary numbers of digits (2.7 trillion as of August 2010), [4] and people began memorizing more and more of the output. The world record for the number of digits memorized has exploded since the mid-1990s, and it stood at 100,000 as of October 2006. [6]
Pi Day is celebrated each year on March 14 because the date's numbers, 3-1-4 match the first three digits of pi, the never-ending mathematical number. "I love that it is so nerdy.
