How do I limit rotations for both positive and negative degrees?

So what I'm trying to do is limit an objects rotation, however, when the object reaches a negative rotation, it snaps to 60 just like it would with a rotation above 60 degrees (my code explains it)

For example whenever the rotation reaches -1 degrees , it snaps to 60 degrees, is there any way to fix this?

(I also thought about the fact that maybe -1 degrees is being detected as 359 degrees, but I'm not sure about that.)

 float currentZ = transform.localRotation.eulerAngles.z;

 
 if (currentZ > 60) {
             currentZ = 60;
             transform.localEulerAngles = new Vector3 (transform.localRotation.eulerAngles.x, transform.localRotation.eulerAngles.y, currentZ);
 }

EDIT:

I figured it out myself, the rotation DOES become 359, so for that reason all I had to do was instead of making it check if currentZ > 60, making it check if currentZ > 60 && currentZ < 180. And of course for the negative rotations make it if currentZ < 300 && currentZ > 180.

I'm just gonna leave this up here for other people with the same question or for suggestions that would work better than my code.
