Here are a couple of controls that simulate an LCD numerical display. You will need to install the fonts for them to work as pictured. You can achieve the same things with which ever font you like but it really only works with mono-spaced fonts.
You can customize each control in the "Advanced" right click menu of the control to set the precision you need or to modify the font size. Note that you can't change the font size without customizing the "background" label font too. Accessing and modifying each component is most easily achieved by changing the z-order of the components using the Ctrl-K, Ctrl+J shortcuts while in tweezer mode
