E (mathematical constant) - Wikipedia, the free encyclopedia
The mathematical constant e is the unique real number such that the value of the derivative (slope of the tangent line) of the function f ( x ) = e x at the point x  = 0 is exactly 1....

Computing the precise value of the number e is a surprisingly mysterious task. We will describe two different ways to do this, even though the full explanation of why the methods work is unfortunately a bit beyond our reach.

What follows are the first 1 million digits of the number e. Actually there are slightly more than 1M digits here. ... We believe these are the most digits ever computed for the number e on or before 1 April 1994. We have computed at least 10 million digits of the number e and several digits of the the square roots of...

The number e was first studied by the Swiss mathematician Leonhard Euler in the 1720s, although its existence was more or less implied in the work of John Napier, the inventor of logarithms, in 1614. Euler was also the first to use the letter e for it in 1727 (the fact that it is the first letter of his surname...

The number e first comes into mathematics in a very minor way. This was in 1618 when, in an appendix to Napier's work on logarithms, a table appeared giving the natural logarithms of various numbers.
