When Was Euler's Number Discovered?

In 1683, Swiss mathematician Jacob Bernoulli discovered the constant e while solving a financial problem related to compound interest.

How was Euler's number discovered?

The constant was discovered by the Swiss mathematician Jacob Bernoulli while studying compound interest. The number e has eminent importance in mathematics, alongside 0, 1, π, and i. All five appear in one formulation of Euler's identity, and play important and recurring roles across mathematics.

Who invented Euler's number?

It was that great mathematician Leonhard Euler who discovered the number e and calculated its value to 23 decimal places. It is often called Euler's number and, like pi, is a transcendental number (this means it is not the root of any algebraic equation with integer coefficients).
