I need to calculate the difference of 2 azimuths (lets say analytical and real azimuth).
There is no issue if both are preatty close in between 0 and 360-eps.
The problem begins if one of them is on the other side of the 0 - if I have analytical to be 359 and actual is 1, the diff is 2 degree. If I'll calculate (analytical - actual) I'll get 358 and if I'll calculate (actual-analytical) I'll get -358 which is wrong for both cases.
Is there some convinient way to do the calculation so that the sign will also be avilable (i.e. who is bigger)
