Math.E

The `Math.E` static data property represents Euler's number, the base of natural logarithms, e, which is approximately 2.718.

Value

$𝙼𝚊𝚝𝚑.𝙴 = e ≈ 2.718 \mathtt{\mi{Math.E}} = e \approx 2.718$

Description

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).

Examples

Using Math.E

The following function returns e:

``````function getNapier() {
return Math.E;
}

getNapier(); // 2.718281828459045
``````
