# Math.LOG2E

## Math.LOG2E

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

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

## 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
```
