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 is coincidental). As a result, sometimes e is called the Euler Number, the Eulerian Number, or Napier's Constant. It was proven by Euler that e is an irrational number, so its decimal expansion never terminates, nor is it ever periodic. An effective way to calculate the value of e is not to use the defining equation above, but to use.
