The `Math.LOG2E` property represents the base 2 logarithm of e, approximately 1.442:

$Math.LOG2E=log2(e)≈1.442\mathtt{\mi{Math.LOG2E}} = \log_2(e) \approx 1.442$

Property attributes of `Math.LOG2E`
Writable no
Enumerable no
Configurable no

## Description

Because `LOG2E` is a static property of `Math`, you always use it as `Math.LOG2E`, rather than as a property of a `Math` object you created (`Math` is not a constructor).

## Examples

### Using Math.LOG2E

The following function returns the base 2 logarithm of e:

``````function getLog2e() {
return Math.LOG2E;
}

getLog2e(); // 1.4426950408889634
``````
