## 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
 | 
						|
```
 | 
						|
