+\* Angle, Angle (degree) and solid angle are simple containers, not containing any functionality to do angle/solid-angle computation such as an overflow after 2*pi. Converting between radians and degree might lose precision, especially if working with `long doubles` because the ratios not precise enough, as they have to be represented as long ints
