Frequently asked questions
What is Euler's number?
A mathematical constant, approximately 2.71828, that's the base of the natural logarithm and appears throughout calculus, compound growth, and probability.
Why is e important?
It's the unique base for which the exponential function e^x is its own derivative, making it fundamental to continuous growth and decay models.
I need pi instead — is there a calculator for that?
Yes — see the Pi Calculator.
