Is haversine_bearing supposed to return -180 to 180?

[kingkong-cmd]

I was expecting to get values from 0 to 360. Is -180 to 180 a convention?

Timely! I just merged #1216 2 days ago.

It hasn't been released yet, but if you are using main you can use the new Haversine::bearing(a, b) to get output in 0...360

See #1210 for more.

Aha, sorry, didnt check the commits. Thats great, and i will just wait for next release. I believe a simple %% 360 fixes it in the meantime.

[michaelkirk]

I think that should be: (bearing + 360.0) % 360.0

[grevgeny]

It’s like a remainder but for Euclidean division, so bearing.rem_euclid(360.0) will work as well to get an output in 0...360

Apologies, I thought rust had a modulo operator %%, but I see now that is not the case. Then I will use one of your suggestions instead.

Edit: I also read #1210 and I wholeheartedly support using stupid and explicit language for docs. Makes life so much easier for idiots like me.
