Forms :: Decimal Entry Rounds Down - Want To Round Up

On one of my Access forms, a specific textbox rounds a value down if the user enters the decimal. The table field bound to it, is a long integer as to not accept decimal values.

For example = user entered .5 rounds to 0
user entered 10.5 round to 10

I would like this to behave in the opposite manner and always round up, but how??? Since users are estimating their hours for specific tasks, I would prefer any decimal value to round to the next integer. I have tried many adjustments to get this working to no avail. I did come across something about key press for decimal and to disallow user to even enter a decimal in this textbox. I would be fine with that solution as well, but could not implement as seen.
