It produces about 14 digits of π per term [134] and has been used for several record-setting π calculations, including the first to surpass 1 billion (10 9) digits in 1989 by the Chudnovsky brothers, 10 trillion (10 13) digits in 2011 by Alexander Yee and Shigeru Kondo, [135] and 100 trillion digits by Emma Haruka Iwao in 2022.

According to its author, it can compute one million digits in 3.5 seconds on a 2.4 GHz Pentium 4. [100] PiFast can also compute other irrational numbers like e and √ 2. It can also work at lesser efficiency with very little memory (down to a few tens of megabytes to compute well over a billion (10 9) digits).
John Machin [2] 100: 1706: William Jones: Introduced the Greek letter ' π ' 1719: Thomas Fantet de Lagny [2] Calculated 127 decimal places, but not all were correct 112: 1721: Anonymous Calculation made in Philadelphia, Pennsylvania, giving the value of pi to 154 digits, 152 of which were correct.
is the number of collisions made (in ideal conditions, perfectly elastic with no friction) by an object of mass m initially at rest between a fixed wall and another object of mass b 2N m, when struck by the other object. [1] (This gives the digits of π in base b up to N digits past the radix point.)
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.

The Gauss–Legendre algorithm is an algorithm to compute the digits of π. It is notable for being rapidly convergent, with only 25 iterations producing 45 million correct digits of π . However, it has some drawbacks (for example, it is computer memory -intensive) and therefore all record-breaking calculations for many years have used other ...
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]
