This tool can be used to show parts of the Euler number e or to search in the long series of numbers. In this tool e has up to 1 million decimals.

The number e is an important mathematical constant that is the base of the natural logarithm. It is approximately equal to 2.71828 and is the limit of (1 + 1/n)^n as n approaches infinity. The number e is also known as Napier's constant, but Euler's choice of the symbol e is said to have been retained in his honor. The constant was discovered by the Swiss mathematician Jacob Bernoulli while studying compound interest.
e is an irrational number, meaning that it cannot be written as the ratio of two integers. Since e is irrational, it has an infinite number of digits in its decimal representation and it does not end with an infinitely repeating pattern of digits.
