Problem with my object that does not stop moving - unity3d

Question

I made a script for moving an object to the position indicated by the mouse click. If I don't choose to click to another location to move towards, I would like to stop my object if it reaches the previously mentioned position. However, the object doesn't stop when reaching the position and it continues moving.
Here is the code I wrote. I would be grateful if somebody knows how to fix this issue.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PlayerController : MonoBehaviour
{
public float moveSpeed;
private Vector3 targetPos;
private Rigidbody2D rb;
private bool isMoving;
private Vector2 direction;
public float changeDirCooldown;
private float changeCool;
private bool canChangeDir;
void Start()
{
rb = GetComponent<Rigidbody2D>();
changeCool=changeDirCooldown;
canChangeDir =true;
}
void Update()
{
if (Input.GetMouseButton(0) && canChangeDir)
{
changeDirCooldown = changeCool;
SetTargetPosition();
}
if (changeDirCooldown<=0)
{
canChangeDir = true;
}
else
{
changeDirCooldown -= Time.deltaTime;
}
}
private void FixedUpdate()
{
if (isMoving)
{
Move();
}
if (this.transform.position == this.targetPos)
{
isMoving = false;
rb.velocity = Vector2.zero;
}
}
private void SetTargetPosition()
{
targetPos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
targetPos.z = transform.position.z;
direction = targetPos - this.transform.position;
direction = direction.normalized;
isMoving = true;
}
private void Move()
{
rb.velocity = direction * moveSpeed;
canChangeDir = false;
}
}

It's probabily a problem with float number tolerance. This line
this.transform.position == this.targetPos
will almost never result to true, so instead you should do something like this:
Mathf.Abs(this.transform.position.x - this.targetPos.x) < float.Epsilon &&
Mathf.Abs(this.transform.position.y - this.targetPos.y) < float.Epsilon
