Die Wikipedia hat die folgende Information zu diesem Codepunkt:
The number e is a mathematical constant, approximately equal to 2.71828, that is the base of the natural logarithm.
The number e is sometimes called Euler's number, after the Swiss mathematician Leonhard Euler, though this can invite confusion with Euler's constant, a different constant typically denoted . Alternatively, e can be called Napier's constant after John Napier. The constant was discovered by the Swiss mathematician Jacob Bernoulli while studying compound interest.
The number e is of great 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. Like the constant π, e is irrational, meaning that it cannot be represented as a ratio of integers, and moreover it is transcendental, meaning that it is not a root of any non-zero polynomial with rational coefficients. To 40 decimal places, the value of e is:
