Math.LN2
En esta página
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
