Subject: how to diferentiate integers with decimals in the IF formulas

I think your question is: how to recognize integral numbers.
One answer:

=IF(INT(A1) = A1, "integral number", "non-integral number")

Caveat: If A1 is the result of a formula that involves non-integral
numbers, the result might appear to be an integral number in
the cell, but it really is not. In that case, it might be better to
write:

=IF(ABS(A1-INT(A1)) < 1E-6, "integral number", "non-integral number")

where you might choose something other than 1E-6, depending
on your tolerance or cell format.

Alternatively, you might set the option Tools Options
Calculation Percision as Displayed. But that might have
unexpected consequences.
