No calculation of Pi is correct, even the ones with trillions of decimal places are approximations. Pi is an irrational number.

The more accurate approximations are only important in things like calculating the curvature of space-time.

The first calculations of Pi were done by calculating the total length of the sides of a polygon and continuing to increase the number of sides until it was almost round.

Several algorithms have been developed for calculating Pi, see https://en.wikipedia.org/wiki/Approximations_of_pi

You calculator stores a value of Pi instead of calculating it each time. That saves time when doing work on the calculator.


355/113 is accurate to the 7th decimal.
