Swiss researchers said Monday they had calculated the mathematical constant pi to a new world-record level of exactitude, hitting 62.8 trillion figures using a supercomputer. “The calculation took 108 days and nine hours” using a supercomputer, the Graubuenden University of Applied Sciences said in a statement.

## How do we know pi is pi?

By definition, pi is the ratio of the circumference of a circle to its diameter. In other words, pi equals the circumference divided by the diameter (π = c/d).

## How far has pi been calculated 2021?

## What is full pi?

Succinctly, pi—which is written as the Greek letter for p, or π—is the ratio of the circumference of any circle to the diameter of that circle. Regardless of the circle’s size, this ratio will always equal pi. In decimal form, the value of pi is approximately 3.14.

## Do numbers repeat in pi?

“We love pi because it’s an irrational number, and its trailing digits don’t repeat.” Pi is an irrational number, sure, because it can’t be expressed as a fraction or ratio. 22/7 will get you close to pi, but not quite there. When written as a decimal number, pi’s digits wander off without repeating.

## Is pi truly random?

Normal not random

The reason we can’t call pi random is because the digits it comprises are precisely determined and fixed. For example, the second decimal place in pi is always 4. So you can’t ask what the probability would be of a different number taking this position. It isn’t randomly positioned.
