If this is just for cosmetic purposes, you could leave out the IF and use
conditional formatting to hide the #N/A when it occurs.

I use a calculation that sometimes (legitimately) returns the error code
#N/A. When this happens, I want a blank stored in the cell. So:
IF(ISNA(calculation),"",calculation)
Is there some way of avoiding the second calculation?
