Function IsFormattedAsWholeNumber(rng As Range) As Boolean
Dim fStr As String
fStr = rng.NumberFormat
If InStr(fStr, ".") = 0 Then
IsFormattedAsWholeNumber = True
End If
End Function
Now use the above function like this...=IsFormattedAsWholeNumber(A1)
The above function will return TRUE if the number 123.45 is custom formatted to show as 123, a whole number.

And again, after changing the number format of any cell if you click on Calculate Sheet, it will recalculate all the functions on the sheet.
'The following function has only one argument i.e. a cell reference

'Checking if the cell contains a whole number and if so, the function will return True
If rng - Int(rng) = 0 Then IsFormattedAsWholeNumber = True
'If above condition is not met, the control passes to the Else statement
Else
'fStr String variable holds the custom number format of the cell
'So if the custom number format is whole number, fStr would be equal to 0
'And if the custom number format is a decimal number, fStr would be equal to 0.0 or 0.00 depending upon the decimal places
fStr = rng.NumberFormat
'Checking if the fStr which holds the custom number format as a string doesn't contain a . (period) in it
'That means the custom number format is 0 i.e. a whole number, hence the function would return True in this case

If InStr(fStr, ".") = 0 Then

End If
End If
End If
End Function
EDITED: TRUE & FALSE wrong way round
