Minutes and Seconds in a text

Question

Hey guys, i am making a CountDown Timer, and it work, but not as i wanted. I made it very simple in C#. It's basically a float that is changed over time, and it is shown in a text. If i set the float to 900 (15 minutes), then the text is going to be shown like 900 normally. What i want to do is, if i set the float to 900, then in the text, it will show something like 15:00. How would i do that? I have no idea of how to start.

This is my script:

 using UnityEngine;
 using System.Collections;
 using UnityEngine.UI;
 
 public class Timer : MonoBehaviour
 {
     public float timeLeft = 900.0f;
     public Text text;
     bool clock;
     private float mins;
     private float secs;
 
     void Update()
     {
         if (timeLeft > 0 && clock == false)
         {
             clock = true;
             StartCoroutine(Wait());
         }
 
     }
 
     IEnumerator Wait()
     {
         timeLeft -= 1;
         UpdateTimer();
         yield return new WaitForSeconds(1);
         clock = false;
     }
 
     void UpdateTimer()
     {
         text.GetComponent<UnityEngine.UI.Text>().text = timeLeft.ToString();
     }
 }

Could someone help me to change the text format so it show things like real minutes and seconds? Thanks in advance! Btw someone said to me that i would need to use math to change the mins and secs variables, but i don't know how to do it and in what it would help actually =\

Just do this:

 int min = Mathf.FloorToInt(timeLeft / 60);
 int sec = Mathf.FloorToInt(timeLeft % 60);
 text.GetComponent<UnityEngine.UI.Text>().text = min.ToString("00") + ":" + sec.ToString("00");

FloorToInt will round the given value down to the nearest integer. So 14.3215 becomes 14.

Dividing your whole time in seconds by 60 gives you minutes but with fractional part so rounding down to int gives you whole minutes

Taking the modulo 60 (division remainder) of the whole time in seconds will give you only the actual seconds Example 885 --> 885 / 60 --> 14 remainder 45. So the time is 14 minutes and 45 seconds.
