title: Double to String keeping trailing zero
body: <p>I've tried converting the double value into a string and using the <code>Replace()</code> method 
   to replace the ',' to '.'.</p>
  
  <p>This works well but only when the trailing digits are not zero, I need zeros in my string, even if the value is 1234.0. This worked well for the decimal values. I have tried to convert the double to decimal but I lose the decimal digits if there are zeros.</p>
  
  <p>I know I'm missing something. I would be grateful for some suggestions.</p>
