Limit Rotation Angle Unity 3D

Question

i'm trying to limit maximum rotation angle and i do not know how to do that.. i am using this code currently, how can i limit maximum rotation angle of object?

    using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class rotObj : MonoBehaviour {

    void Update () {
        var dir = Camera.main.ScreenToWorldPoint (Input.mousePosition) - transform.position;
        var angle = Mathf.Atan2 (dir.y, dir.x) * Mathf.Rad2Deg;
        var rot = Quaternion.AngleAxis (angle, Vector3.forward);
        transform.rotation = rot;
    }

}

What you have to do is just check if the rotation is bigger than the rotation that you want to be max. If it's bigger, then set it to max and if it's not then just leave it. Code should be something like:

currentRotation = Mathf.Min (currentRotation, maxRotation);

This will take the smaller one. If you are limiting it to mininum rotation. Instead use:

currentRotation = Mathf.Max (currentRotation, minRotation);

I haven't tested this code but i think it should work!
