I input dblTargetValue and dblLowScoreValue as Double into a VBA
function and show the output as a string, like this:

Dim strOutput as string
strOutput = CStr((dblTargetValue - dblLowScoreValue))

I want to round the output so that it doesn't show too many decimals,
like this:
* If dblTargetValue - dblLowScoreValue = 0 decimals, show 0 decimals
* If dblTargetValue - dblLowScoreValue = 1 decimals, show 1 decimal
* If dblTargetValue - dblLowScoreValue = 2 decimals, show 2 decimals
* If dblTargetValue - dblLowScoreValue = 3 decimals, show 3 decimals

I really need help with this immediately because I have a deadline to
keep so I'm very grateful for help!
