## 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
|
||
|
```
|
||
|
|
