I am trying to write a UI to reflect the current orientation of the robot using the tf information published. While printing the angle value using the getangle() function provided by tf::quaternion i noticed that the value is not in degree. I also noticed from the API that the angle() function returns half angles.

Do anyone knows what unit of measurmen does the getangle() function returns the angle value in?

Angle units should be radians unless otherwise specified. Defaults are in REP 103
