# llAxisAngle2Rot

*LSL function*

```lsl
rotation rotation llAxisAngle2Rot(vector axis, float angle);
```

- `vector axis`: Axis vector to rotate around.
- `float angle`: Angle to rotate, in radians.

- Returns: `rotation`
- Energy: 10

**axis** need not be [normalized](/functions/llVecNorm/), only the direction is important.

**angle** need to be between the value 0<angle<[PI](/constants/PI/) (higher values than [PI](/constants/PI/) lead to 2\*PI-angle)

, because a rotation is not really a rotation (it is more of a rigid motion/mirroring)

,the final destination is the rotation.

(in other words: it doesn't matter wether you rotate left by 90 degrees or right by 270 degrees it will return the same rotation)

Returns a [rotation](https://wiki.secondlife.com/wiki/rotation) that is a generated **angle** about **axis**

## Examples

<summary>Example 1</summary>

```lsl
default
{
    state_entry()
    {
        vector axis = <0.0, 0.0, 1.0>;
        float angle = 90.0 * DEG_TO_RAD;
        rotation rot = llAxisAngle2Rot(axis, angle);
        vector euler = llRot2Euler(rot) * RAD_TO_DEG;

        llOwnerSay((string) euler);
        //Says <0.0, 0.0, 90.0> since it is rotating 90 degrees on the Z axis caused by the 1.0 placed in the Z vector spot.
    }
}
```
