The **`Math.LN2`** static data property represents the natural logarithm of 2, approximately 0.693:

{{InteractiveExample("JavaScript Demo: Math.LN2", "shorter")}}

```js interactive-example
function getNatLog2() {
  return Math.LN2;
}

console.log(getNatLog2());
// Expected output: 0.6931471805599453
```

## Description

Because `LN2` is a static property of `Math`, you always use it as `Math.LN2`, rather than as a property of a `Math` object you created (`Math` is not a constructor).

## Examples

### Using Math.LN2

The following function returns the natural log of 2:

```js
function getNatLog2() {
  return Math.LN2;
}

getNatLog2(); // 0.6931471805599453
```
