pi: command not found

The pi command is a command-line tool that calculates the mathematical constant π (pi) to a specified number of decimal places. The calculation of π is based on Archimedes’ method, which involves inscribing and circumscribing polyggonal shapes around a circle and successively increasing the number of sides to estimate the value of π.

The pi command can be used in a variety of environments, including Unix-like systems and Windows command prompt, to quickly compute the value of π to the desired precision. For example, to calculate π to 20 decimal places, you would run the following command:

# pi 20

This would output the following result:

3.1415926535897932384

The pi command is a useful tool for anyone who needs to perform calculations involving π, such as students, researchers, and engineers. Additionally, it is a fun way to explore the properties of the mathematical constant and learn more about the fascinating history of its discovery and computation.
