# Math.abs()

The **`Math.abs()`** function returns the absolute value of a number.


## Syntax

```js
Math.abs(x)
```

### Parameters

- `x`
  - : A number.

### Return value

The absolute value of `x`. If `x` is negative (including `-0`), returns `-x`. Otherwise, returns `x`. The result is therefore always a positive number or `0`.

## Description

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