Check rotation for a Rigidbody2D

Hello, i am making a 2D game where im trying to make swimming mechanics, think DK tropical freeze.

I have rotation for the character as a vector, and when the player object reaches the desired rotation, i want to add force.

However rigidbody2D stores its rotation as a single float value that dosent wrap around. How would i go about making something that can check if the rotation of the rigidbody2D has reached its desired rotation?

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class Swimmer : MonoBehaviour
 {
 
     public float maxSpeed = 5;
     public float rotationSpeed = 5f;
     public Player player;
 
     
 
     public Transform orientationTarget;
 
     private Vector3 dinput;
     Vector3 velocity;
     
     Rigidbody2D rigidbody;
 
 
 
     // Start is called before the first frame update
     void Start()
     {
         rigidbody = GetComponent<Rigidbody2D>();
         
     }
 
     }
     private void FixedUpdate() {
         Move();
     }
 
     public void Move() {
 // if there is input
         if (Input.GetAxis("Vertical") != 0 || Input.GetAxis("Horizontal") != 0) {
 
 // get input as a vector 3
             dinput = new Vector3(0, 0, Mathf.Atan2(Input.GetAxis("Vertical"), Input.GetAxis("Horizontal")) * 180 / Mathf.PI - 90);
 
             
 //rotate the rigidbody over time
             rigidbody.MoveRotation(Mathf.LerpAngle(rigidbody.rotation, dinput.z, Time.deltaTime * rotationSpeed));
 
 
             orientationTarget.eulerAngles = dinput;
             
 //on the output is out problem, the rigidbodies rotation "wraps around".
 //how do we make something that allows us to check if we have reached
 //our desired rotation?
             Debug.Log(rigidbody.rotation +"      "+ orientationTarget.rotation + "  "+ dinput.z);
             
 //the problem occurs before this. But the intention of this code is to
 //compare if the rigidbodies rotation is in the ballpark (-+10 degrees)
 //of the target rotation.
             if (rigidbody.rotation <= dinput.z -10f || rigidbody.rotation <= dinput.z +10f) {
                 rigidbody.AddForce(dinput*10f);
                 }
 
 
 
         }
     }
