*LSL function*

```lsl
vector vector llRot2Axis(rotation q);
```

- `rotation q`: Rotation to evaluate.

- Returns: `vector`
- Energy: 10

Use in conjunction with [llRot2Angle](/functions/llRot2Angle/).

To undo use [llAxisAngle2Rot](/functions/llAxisAngle2Rot/) or [llAxes2Rot](/functions/llAxes2Rot/).

Returns a [vector](https://wiki.secondlife.com/wiki/vector) the rotation axis represented by **rot**

```lsl title="How to use" frame="terminal"
vector result = llRot2Axis(ZERO_ROTATION);
```
