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 […]
