# ABS
<a name="sql-reference-abs"></a>

Returns the absolute value of the input argument. Returns `null` if the input argument is null.

```
ABS ( {{<numeric-expression>}}  {{<interval-expression>}}
      )
```

## Examples
<a name="sqlrf_abs_examples"></a>


| Function | Result | 
| --- | --- | 
| ABS(2.0) | 2.0 | 
| ABS(-1.0) | 1.0 | 
| ABS(0) | 0 | 
| ABS(-3 \* 3) | 9 | 
| ABS(INTERVAL '-3 4:20' DAY TO MINUTE) | INTERVAL '3 4:20' DAY TO MINUTE | 

If you use `cast as VARCHAR` in SQLline to show the output, the value is returned as `+3 04:20`.

```
 values(cast(ABS(INTERVAL '-3 4:20' DAY TO MINUTE) AS VARCHAR(8)));
