## Math

`Math` is a standard built-in object to JavaScript that contains mathematical constants and functions as properties and methods. Most notably it contains the constants π and Euler's constant and functions such as `floor()`, `round()`, `ceil()` and many more.

### Example
The following example shows how to use the `Math` object to write a function that calculates the area of a circle:

```javascript
function calculateCircleArea(radius) {
  return Math.PI * Math.pow(radius, 2);
}
calculateCircleArea(1); // 3.141592653589793
```
