thanks for your answer. I might prefer your solution simply for its brevity.
However, there are also some sign "problems":
for the angle from -10 to 180 I was expecting +170, but your solution
and for (to:)'190' (from) '-10' expected: '160' , yours returns -160.
I have a list of 30 test cases, which these are the only 2 were yours
gave unexpected results regarding the sign -- besides the fact that
yours always returns -180 instead of +180, but that is obviously not
