The mathematical constant e is the base of the natural logarithm. It is occasionally called Euler's number after the Swiss mathematician Leonhard Euler, or Napier's constant in honor of the Scottish mathematician John Napier who introduced logarithms. (e is not to be confused with γ – the Euler-Mascheroni constant, sometimes called simply Euler's constant.) The number e is one of the most important numbers in mathematics, alongside the additive and multiplicative identities 0 and 1, the imaginary unit i, and π, the circumference to diameter ratio for any circle. It has a number of equivalent definitions; some of them are given below. The numerical value of e truncated to 20 decimal places is: 2.71828 18284 59045 23536

e is a constant term used in exponential growth and decay functions.
An example is the compound interest (continuous) function,
A = Pe^(rt).
They are also used in logarithms. The natural log, ln, is log base e.
