Does it help to use the inputmask property?

>I have put a spinner control on a form that accepts a user's selection for number of hours. I need the number of hours to increment by 1/2 hour (0.5).

>Apparently the spinner is rounding, because it displays zero until you click the up arrow twice, then it displays 1.

>Also, the spinner text box shows 0000001, 0000002, etc.
