You'll probably need to do something like this using jQuery (or the javascript framework of your choice). If you have textboxes similar to these:

<input type="text" class="decimal" value="0.00"/>

Then you can add a couple of event handlers for when users enter and exit these textboxes:

$('input.decimal').focusin(function() {
	if ($(this).val() === '0.00') {
  	$(this).val('');
  }
});
$('input.decimal').focusout(function() {
  var value = parseFloat($(this).val());
	if (isNaN(value)) {
  	$(this).val('0.00');
  } else {
  	$(this).val(value.toFixed(2));
  }
});

You'll probably need to add some extra code to cover pasting into the text boxes. You can take a look at an example on jsfiddle[^].
