Convert Decimal value to Hours & Minutes; Also subtract two Hours/Minutes value from the another
<p>I have two decimal text boxes on the ASP.Net page:</p>

<pre><code>Balance: 200.00 (200 Hrs and 00 Minutes)
TextBox1 = 75.30 (75 Hrs and 30 Minutes)
(After entering the value in TextBox1; the function should calculate the difference between Balance - TextBox1)
TextBox2:  (based on 60 min per hour) = 124.30 (124 Hrs and 30 minutes)
</code></pre>
