Google Engineer Determines 31.4 Trillion Digits Of Pi On Pi Day And Held A World Record.


14th March well known as Pi Day. Pi is a symbol used in mathematics to represent a constant- A ratio of the circumference of a circle to its diameter. The value of Pi is approximately 3.14159. But this Pi day, a Google employee by the name of Emma Haruka Iwao made use of Google Compute Engine- running on Google Cloud – for calculating the value of Pi to 31.4 trillion decimal places

Since Pi is an irrational number, so there is no end to how many digits of Pi can be calculated. We all know it as 3.14 but math and science constantly work to find the more correct and more digits of Pi, For that they use supercomputers

Google employee Emma Haruka Iwao has used Google Compute Engine powered by Google Cloud to calculate the most accurate value of Pi which is 31,415,926,535,897 digits. The first time the Google cloud is used to calculate the value of Pi of this magnitude, Emma well use the power of the cloud for the task.

About Pi Value Calculation

To calculate the value of Pi, Emma used an application called y-cruncher on 25 Google Cloud virtual machines. For calculation of Pi it requires a lot of storage an memory. Her calculation required 170 terabytes of data to complete which equal to the entire Library of congress prints collection.


Emma calculations took the virtual machines about 121 days to complete. The main problem is during the whole time of calculations Googles Cloud infrastructure kept the server going. If there had been an issue with the server such that any failure or interruption, it would have disrupted the calculation.

Emma has created a big moment for her life by holding the world record for calculating the most accurate value of Pi. The previous value of Pi was around 9 trillion decimal places.
