The plan goes like this: - eeschema still uses int in decidegrees - all the other things internally use double in decidegrees (or radians in temporaries) - in pcbnew UI the unit is *still* int in decidegrees The idea is to have better precision everywhere while keeping the user with int i angles. Hopefully, if a fractional angle doesn't come in from the outside, everything should *look* like an integer angle (unless I forgot something and it broke) When the time comes, simply updating the UI for allowing doubles from the user should be enough to get arbitrary angles in pcbnew.
