calculate a percentage into a decimal? (HP-Bar)

hey gang! I have calculated my Player HP into 100 %.
I’m trying to translate this into decimals so 100% = 1 80% = 0.8 act
So i can use this number in Imagefill for a HP bar since Fillamount Only likes decimals :smiley:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class PlayerHealth : MonoBehaviour {

	public float playerhealth;
	public float MaximumPlayerHealth;
	public float PlayerHealthPersentage;
	public float PlayerFloatDecimal;

	public Image PlayerHP; 
	public IndavidualScore Score;
	public GameObject Missioncontroll;

	public void Start (){

	}

	public void LateUpdate (){

		// Calculate HP get 100%
		PlayerHealthPersentage = playerhealth / MaximumPlayerHealth * 100;
		//????????????????????_______________________________________________
		//Set 100% to a decimal 100 = 1 80 = 0.8 act.....
		  = PlayerFloatDecimal;   //????????????????????
		//????????????????????_______________________________________________

		if (Missioncontroll == null) {
			Missioncontroll = GameObject.FindGameObjectWithTag("MissionControll");
			Score = Missioncontroll.GetComponent<IndavidualScore> ();
		}

		PlayerHP.fillAmount = PlayerFloatDecimal; //Display HP BAR XD    

		if(playerhealth < 1){
			Score.Lives -= 1;
		}
	}


}

You divide it by 100??
