Q:
# What is "e" in mathematics?

**The number "e" in mathematics is often called Euler's number, named after Swiss mathematician Leonhard Euler.** Euler originated the notation f (x) for a function, i for the square root of -1 and ? for pi.

An irrational number cannot be expressed as a simple fraction, and it has decimal places that go on forever without repeating. The number e is an irrational number with a starting value of 2.171818459045. The Euler number was first introduced by John Napier in the 1600s, who used it in his theory of the development of logarithms. Leonhard Euler, however, was the first to use the symbol "e." The Euler number is the natural base for exponential functions and logarithms. It is used in continuous compounding for loans and investments, and it is known to one trillion digits of accuracy.
