float number displayed as an int? or at least on the health bar

So I got a health bar, hunger bar, and thirst bar. everything is good; the thirst and hunger goes down throughout time. Also got it hooked up to the canvas, so I see my visual hunger and thirst bars gradually go down, along with the %.

problem is, it displays all these crazy ass decimal numbers after the decimal. I want to cut it down to 2 digits after the decimal, or anything like that.

and in order for the visual bars to be hooked up to the invisible variable numbers, it has to be a float?

heres the script:

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

public class DamageAI : MonoBehaviour { public float playerHealth = 100; private float maxplayerHealth = 100; private float damage = 8;

 //New shit xD
 private EnemyAI DAI;
 private EnemyAI EAI;
 public AudioSource aSource;
 private int healthReg = 1;
 bool isRegenHealth;

 public float hunger = 100f;
 private float maxHunger = 100;
 public float thirst = 100f;
 private float maxThirst = 100;

 private float hungerSpeedMultiplier = 0.055f;
 private float thirstSpeedMultiplier = 0.155f;


 void Start()
 {
     UpdateHealthBar();
     aSource = GetComponent<AudioSource>();
     EAI = gameObject.GetComponent<EnemyAI>();
     DAI = gameObject.GetComponent<EnemyAI>();
 }

 private void Update()
 {
         {
             UpdateHealthBar();
             CheckDeath();
             UpdateHNT();
         }
     if (hunger > 0)
     {
         hunger -= Time.deltaTime * hungerSpeedMultiplier;
     }
     if (thirst > 0)
     {
         thirst -= Time.deltaTime * thirstSpeedMultiplier;
     }
 }

 private void CheckDeath()
 {
     if (playerHealth <= 0)
     {
         Die();
     }
 }

 private void Die()
 {
     Destroy(GetComponent<Movement>());
     Destroy(GetComponent<EnemyAI>());
     Destroy(GetComponent<DamageAI>());
 }

 private void UpdateHealthBar()
 {
     if(playerHealth != maxplayerHealth && !isRegenHealth)
     {
         StartCoroutine(RegainHealthOverTime());
     }
     if (playerHealth > maxplayerHealth)
     {
         playerHealth = maxplayerHealth;
     }
 }

 private IEnumerator RegainHealthOverTime()
 {
     isRegenHealth = true;
     while (playerHealth < maxplayerHealth)
     {
         Healthregen();
         yield return new WaitForSeconds(3);
     }
     isRegenHealth = false;
 }

 public void Healthregen()
 {
     playerHealth += healthReg;
 }

 private void UpdateHNT()
 {
     if(hunger > maxHunger)
     {
         hunger = maxHunger;
     }
     if(thirst > maxThirst)
     {
         thirst = maxThirst;
     }

         if (hunger <= 0 && (thirst <= 0))
         {
             playerHealth -= Time.deltaTime / damage * 16;
         }

         else if (hunger <= 0 || thirst <= 0)
         {
             playerHealth -= Time.deltaTime / damage * 16;
         }

         if(hunger < 50f)
     {
         EAI.lookAtF();
         EAI.eatPlease();
     }

         if(thirst < 50f)
     {
         DAI.lookAtD();
         DAI.drinkPlease();
     }
     }

 void OnCollisionEnter(Collision _collision)
 {
     if (_collision.gameObject.tag == "Enemy")
     {
         playerHealth -= damage;
         aSource.Play();
         {
             if (playerHealth < 0)
             {
                 playerHealth = 0;
             }
             UpdateHealthBar();
         }
     }
 }

 public void HealDamage(float heal)
 {
     playerHealth += heal;
     if (playerHealth > maxplayerHealth)
         playerHealth = maxplayerHealth;

     UpdateHealthBar();
