Fun Fact
Pi is an irrational number, meaning its decimal expansion never ends and never repeats. Trillions of digits have been computed, yet they never form a pattern.
Historical Context
The calculation of π dates back over 4,000 years, with early approximations found in ancient Babylonian and Egyptian texts. Modern algorithms, like the spigot method used here, allow digits of π to be computed efficiently one at a time using purely arithmetic operations.
