Chronology of computation of π

The table below is a brief chronology of computed numerical values of, or bounds on, the mathematical constant pi (π).

As of July 2024, π has been calculated to 202,112,290,000,000 (approximately 202 trillion) decimal digits.

The last 100 decimal digits of the latest world record computation are:[1] "He puts on (the circular site) four (bricks) running eastwards 1; two behind running crosswise (from south to north), and two (such) in front.

The two at the back then are the thighs; and the two in front the arms; and where the body is that (includes) the head.

The Moon is handed down by memory to be eleven thousand yojanas in diameter.
