# llEuler2Rot

*LSL function*

```lsl
rotation rotation llEuler2Rot(vector vec);
```

- `vector vec`: Vector of Euler angles to convert, in radians.

- Returns: `rotation`
- Energy: 10

Returns the quaternion representation of the Euler angles (in radians) within vec.

Returns a [rotation](https://wiki.secondlife.com/wiki/rotation) representation of the [Euler Angles](https://en.wikipedia.org/wiki/Euler_Angles) `v`.

```lsl title="How to use" frame="terminal"
rotation result = llEuler2Rot(ZERO_VECTOR);
```

## Specification

The [Euler](https://wiki.secondlife.com/wiki/Category:LSL_Euler) angle vector (in radians) is converted to a rotation by doing the rotations around the 3 axes in Z, Y, X order. So `llEuler2Rot(<1.0, 2.0, 3.0> * DEG_TO_RAD)` generates a rotation by first rotating 3 degrees around the global Z axis, then rotating the result around the global Y axis, and finally rotating that 1 degree around the global X axis.

## Examples

<details open>
<summary>Example 1</summary>

```lsl
default
{
    state_entry()
    {
        vector input = <73.0, -63.0, 20.0> * DEG_TO_RAD;
        rotation rot = llEuler2Rot(input);
        llSay(0,"The Euler2Rot of "+(string)input+" is: "+(string)rot );
    }
}
```

</details>

## Notes

```lsl
v/=2;
rotation k = <0.0, 0.0, llSin(v.z), llCos(v.z)> * <0.0, llSin(v.y), 0.0, llCos(v.y)> * <llSin(v.x), 0.0, 0.0, llCos(v.x)>;
```
