I looking for an easy formula that will do the following procedure:
[....]
If cell A1 contains a value (0 - infinity) show value of A1,
if not show value in cell A2
Often, the following is sufficient:
=IF(A1<>"", A1,A2)
But if A1 might contain other text and you want A2 in that case, then you
need:
=IF(ISNUMBER(A1),A1,A2)
I also note that you say "0 to infinity". If A1 might contain a negative
number and you want A2 in that case as well, then you need one of the
following:
=IF(AND(A1<>"",A1>=0),A1,A2)
=IF(AND(ISNUMBER(A1),A1>=0),A1,A2)
Finally, if A1 might contain an Excel error (e.g. #NUM, #DIV/0 or #NA) and
you want A2 in that case as well, then you need one of the following:
=IF(ISNUMBER(A1),A1,A2)
=IF(ISNUMBER(A1),IF(A1>=0,A1,A2),A2)
But generally, is preferrable to avoid Excel errors in a cell.
