This tool stores 10,000 verified decimal digits of π. They are embedded directly in the page — no internet request is made when you display them.
e ≈ 2.71828 is the base of the natural logarithm. It appears in compound interest (A = Pe^rt), normal distributions, and differential equations. Like π, its decimal expansion is infinite and non-repeating.
Pi is believed to be a normal number — meaning every sequence of digits appears with equal frequency in the long run. This would mean your birthday, phone number, or any string is somewhere in π. It is widely assumed but not yet proven.
