Scrollbar Scroll Scale

is it possible to change the scroll scale so it snaps to whole numbers rather then going into decimals

examples

(#) = posible positions for example

normal scrollbar (scale = 0 - 5 ):

[----(1)-----(2)----]

1 = 2.15479

2 = 4.52154

scrollbar i want (scale 0 - 5):

[----(1)----(2)----]

1 = 2.0

2 = 4.0

you should be able to just round the scroll position it returns before passing back in the next frame, like this...

var barRect:Rect=Rect(0,0,200,16);
var scrollPos:float=0;

function OnGUI()
{
   scrollPos=GUI.HorizontalScrollbar(barRect,scrollPos,1,0,5);

   //round positions off so they "snap" to integer positions
   scrollPos=Mathf.Round(scrollPos);   
}

:Edit: realized I missed half the point there; easiest way to get the rest would just be to round as I said above and multiply the scrollPos by 2 to get a scaledScrolledPos.
