Format a string for cents only in C#

I have a dollar amount, 23.15. I want to format it so that I can return just .15 or 15 as I want to place just the cents in an html <sup> tag.

To return dollars only, I used {0:C0} or without the $ sign {0:N0}

Edit: Apparently {0:C0} and {0:N0} will not work for me as they round to a whole number :(

class Program { static void Main(string[] args)

    {

        double Num;
        // declaring "Num" as a double

        Console.WriteLine("Please enter dollar and cents amount\nExample: 4.52");
        //This bit of code informs the user what type of information you want from them

        Num = double.Parse( Console.ReadLine());
        //assigns "Num" to the users input and sets the user input as numerical value and stores it in the temporary memory

        Console.WriteLine("You have {1} dollars and {2} cents from {0:c}.", Num, WhyAreWeDoingThis(ref Num), Num);
        //returns the values requested and sends "Num" through the program to separate dollars from cents.
        //first: off in{0:c} it takes the original user input and gives it the dollar sign$ due to the additional code to the left of the zero as shown {0:c}
        //second: "Num" is sent to the WhyAreWeDoingThis Method through the reference method "ref" where the dollar amount is separated from the cent amount
        //*Note* this will only return the dollar amount not the cents*
        //Third: the second "Num" referred to at this point is only the remaining cents from the total money amount. 
        //*Note* this is because the program is moving "Num" around as a stored value from function to function not grabbing the users original input every time.

        Console.ReadLine();
        //this keeps the program open

    }
    static int WhyAreWeDoingThis(ref double A)
        // reference method
        //*Note* it is set as a "static int" and (ref double)

    {
        int dd = (int)A;
        //this turn the double into a temporary integer by type casting for this one operation only.
        A = A % dd;
        //Separates the dollars from the cents leaving only the cents in the "Num" value through the Modulus Operand.
        return dd;
        //returns the dollar amount.
    }
}

If you need string with html tags you can use something like this:

 var decimalValue = 23.15m;
 string value2 = decimalValue.ToString("$ #.<sup>##</sup>"); //$ 23.<sup>15</sup>

Also if you want amount with cents instead of 

var value =  String.Format("{0:C0}", decimalValue); // $23

use

 var value =  String.Format("{0:C2}", decimalValue); // $23.15

Zero after 'C' in '{0:C0}' format means number of signs after point.

Not the mainstream way but will work :)

dollarAmount - Math.Floor(dollarAmount)

will get you cents (in your sample will get .15).
