Back # Math.E

The ** Math.E** property represents the base of natural logarithms, e, approximately 2.718.

$$\backslash mathtt\{\backslash mi\{Math.E\; =\; e\; \backslash approx\; 2.718$$

Because `E`

is a static property of `Math`

, you always use it as `Math.E`

, rather than as a property of a `Math`

object you created (`Math`

is not a constructor).

`Math.E`

The following function returns e:

function getNapier() { return Math.E; } getNapier(); // 2.718281828459045
