The last 100 decimal digits of the latest world record computation are: [1] 7034341087 5351110672 0525610978 1945263024 9604509887 5683914937 4658179610 2004394122 9823988073 3622511852 Graph showing how the record precision of numerical approximations to pi measured in decimal places (depicted on a logarithmic scale), evolved in human history.
To compute π to 100 decimal places, he combined his formula with the Taylor series expansion for the inverse tangent. (Brook Taylor was Machin's contemporary in Cambridge University.) Machin's formula remained the primary tool of pi-hunters for centuries (well into the computer era). Several other Machin-like formulae are known.
which he used to compute π to 100 decimal places. [1] [2] ... In Pi Day 2024, ... Since this is a relative metric, the value of k can be ignored.
With a correct value for its seven first decimal digits, this value remained the most accurate approximation of π available for the next 800 years. [58] The Indian astronomer Aryabhata used a value of 3.1416 in his Āryabhaṭīya (499 AD). [59] Fibonacci in c. 1220 computed 3.1418 using a polygonal method, independent of Archimedes. [60]
Of some notability are legal or historical texts purportedly "defining π" to have some rational value, such as the "Indiana Pi Bill" of 1897, which stated "the ratio of the diameter and circumference is as five-fourths to four" (which would imply "π = 3.2") and a passage in the Hebrew Bible that implies that π = 3.

A sequence of six consecutive nines occurs in the decimal representation of the number pi (π), starting at the 762nd decimal place. [1] [2] It has become famous because of the mathematical coincidence, and because of the idea that one could memorize the digits of π up to that point, and then suggest that π is rational.
