Null value into an integer variable

["Mayost Sharon" <sharon@xxxxxxxxx>]

Hello


Public Sub Main()
  
  Dim sVar As String
  Dim iVar As Integer

  sVar = "gb"
  iVar = 3
  
  sVar = Null
  iVar = Null
  
End


When I put an Null value into a variable of type string I don't get an error and the variable gets a value of ""

But when I put an Null value into a variable of integer type it gives an error

Is this normal?

Thank you
