Summary

Function: float llRot2Angle( rotation rot );
171 Function ID
0.0 Delay
10.0 Energy

Returns a float that is the rotation angle represented by rot

• rotation rot

Use in conjunction with llRot2Axis.
To undo use llAxisAngle2Rot.

Caveats

This always returns a positive angle <= PI radians, that is, it is the unsigned minimum angle. A rotation of 3/2 PI radians (270 degrees) will return an angle of PI / 2 radians, not -PI / 2. Search JIRA for related Bugs

Deep Notes 

float Rot2Angle(rotation a)
{
    return llAcos(llFabs(a.s) / llSqrt(a.x * a.x + a.y * a.y + a.z * a.z + a.s * a.s)) * 2.0;
}
