How do we stop the method in unity?

[Analeea]

Under this violin, the background has to change its form (what it does) but in Enter, there is a computation that finds the difference between the real size and the right and ends only if the difference is zero, which will never occur because of the calculation. Now I have to either forcefully stop the method or somehow implement the completion condition. The problem is that the variable i (the true size of the axis x) is never equal to 2 (numerical size) and is fixed to 1.99999999... (A Change actually comes to a very small Cyber Bowl) Can I do something about it?

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.EventSystems;
public class Button : MonoBehaviour, IPointerEnterHandler, IPointerExitHandler

{

[Header("Set manualy")]

[Tooltip("This is the backline, that will be activaited when the mouse is on button")]

public GameObject Background;

[Tooltip("Set how long the line will become, when mouse is on it")]

public float      Selected;

public float      Speed;

[Header("Sets automatically")]

public RectTransform rt;

public float      Change;

public float      i;
void Awake() {
    rt = Background.GetComponent<RectTransform>();
    i = 1;
}


public void OnPointerEnter(PointerEventData eventData) {
    Invoke("Enter", 0f);
}

void Enter() {
    print("Still using Enter");
    Change = Selected - i;

    i += Change * Speed;
    rt.anchorMax = new Vector2(i, 1);
    if (Change == 0) { Invoke("Enter", 0f);}
}


public void OnPointerExit(PointerEventData eventData) {
    Invoke("Exit", 0f);
}

void Exit() {

}

}

Problem float It's something they have. Read them here: https://ru.stackoverflow.com/q/417453/191482

So, as an option, we need to compare. Change Not with the exact value of 0, but with some delta you'd like. I mean, for example. if (Change < 0.1)
