try

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    'Activity.LoadLayout("Layout1")
    Log( isDecimal("12.3"))
    Log (isDecimal("12"))

End Sub


Sub isDecimal (s As String) As Boolean
    Dim d As Double
    Dim i As Int
    Try
        d = s
        i = s
        If d-i > 0 Then
            Return True
        Else
            Return False   
        End If
       
    Catch
        Return False
    End Try
End Sub

What exactly are you trying to check with IsDecimal? Do you want to test whether the number is a whole number or not?

You can use this code:

Sub IsDecimal(s As String) As Boolean
 Return IsNumber(s) And Floor(s) = s
End Sub
