Hi Otto,

Just to add to Bob's excellent suggestion, you may want to use error
handling in the case that Int or CInt raises an error:

Public Function gbIsInt(rvValue As Variant) As Boolean
On Error Resume Next
gbIsInt = (rvValue = CInt(rvValue))
On Error GoTo 0
End Function

My end goal is to test a cell value, via VBA, to see if it is an
integer. The worksheet Mod function works like this:
Mod(D6,1) returns a 0 if D6 is an integer.
The VBA Mod function rounds all numbers first so I can't use that.
So I used:
MsgBox Application.WorksheetFunction.Mod(Range("D6"),1)
I was hoping to get a 0 if D6 is an integer.
I got an error message that said "Object doesn't support this method".
Where did I go wrong? Thanks for your help. Otto
