ghayas-

           Here are your answers-

1) You need to use "Fract/Exp String to Number" instead of all of your "Decimal String to Number"

2) The screen goes blank because you reinitialize the String Local Variable everytime an operation button is pressed. See attached picture for what I'm talking about.

Hope this helps. Happy Wiring!!

It is possible to do it by programming properly using shift registers. I would recommend that you go through some of the training materials before you build an application of this kind. You might also want to go through the Getting Started with LabVIEW manual that is available on the Getting Started window when LabVIEW starts up. Also, you should be using event structures when doing user interface. Here is an example of a calculator that was built in LabVIEW.
