I’m at a bit of a coders block, and I’m sure it’s quite simple. 😛

I tried using the following:

```auto
((angle-180)%360) + 180

```

But for angles \< 180 degrees, it works just fine, but after that it get’s a little funny. I know why it’s doing that, I’m just looking for a way to fix it.

Is there any way to do it quickly without 6 lines of codes containing if statements? The code should be as efficient as possible.
