Rotation Value ist not the same as given in the driver output I am just trying to set up a dynamic circular array of objects. To keep it as dynamic as possible, I want to make my helpers empty z rotation driven by a driver. The Scripted Expression looks like this:  360/count while count is the count value set in the arrays modifier on my object.

The final value calculated in the driver is correct.(45 in case I have a count of 8). The actual value set in the rotation property is different. See the Screenshot below.



Am I missing something?
While all angles entered into the transform input field are interpreted as degrees, when you set the value in a script or driver it's interpreted as radians.



Your driver sets the rotation to 45 radians which is about 2578 degrees. The expression 2*pi/count should provide you with the desired angle.
