How to identify 2 decimal places?

I am by no means an expert or a computer scientist. So my explanation may be misleading or incorrect, but I will try to explain to the best of my ability.

One thing about floating point notation is that floats and doubles will never, or rarely only have 2 decimal places. Even if you set a double to 1.22, it may be stored in memory differently, It's possible that the value will be stored as 1.22000000000001 instead. So this is something that needs to be considered.

 //if numbers have 2 decimals in it then display it
 void printAllNumbersWithOnly2Decimals()
 {
     for(int i=0; i<countTime.Count; i++)
     {
         double difference = countTime[i] - double.Parse(countTime[i].ToString("0.00"));

         if (difference < 0) difference *= -1;  //Mathf.Abs() substitute
         if (difference <= double.Epsilon)
         {
             Debug.Log("Number: " + countTime[i] + " has 2 decimal places");
         }
     }
 }

@ tapirlaut man you have blowed up my mind i been working all day long till i found out the way :

 double [] countTime = new double[]{1.1,1.22,1.333,44} ;
 void Start () 
 {
     printAllNumbersWithOnly2Decimals ();
 }
 
 void printAllNumbersWithOnly2Decimals()
     {
         for(int i =0; i<countTime.Length;i++)
         {
             string e = countTime [i].ToString ();
             if (e.Contains(".") && e.IndexOf(".") >= e.Length-3) //delete the > sine if you want only 2 decimal places but don't delete it if you want also 1 decimal places.
             {
                 print (e);
             }
             else if(!e.Contains(".")) // make sure printing numbers that don't have decimal places delete if not necessary.
             {
                 print (e);
             }
         }
     }
