Calculating angle difference

I'm trying to calculate the difference between 2 angles, but if i use the .angle expression, as you may expect, it doesn't work well, because it reaches 360 and then jumps to 0. So for example, is angle 1 is, say, 345, and angle 2 15, it calculate the difference of 330, while it is just 30.

Is there another way to do this?

use anglediff(angle1,angle2)

Wow, why didn't i find it, i've searched for hours for an expression xD ty!
