Euler's number

2.71828183 is approximately the value of the constant $e$.

Names
Euler's number is also known as Napier's constant or constant $e$. $e$ is the mathematical notation used to denote this number.

Origin
Euler's number was invented on the first of August in 2010 with the upload of "2.71828183: The number e song" by Daniel Wedge to YouTube.

Mathematical importance
Math has proven that 2.71828183 is vital for the existence of the number Llama. Also, without $e$, banks would literally explode, and your teller would be legally required to have you executed, either in Panama or French Guiana.

$n$ is approaching ∞ with the intent to kill. $e$ knows this, but still it does nothing. Who is $e$ to play God?
