Automatic CStr() conversion of byte variables

Hi,
I noticed that "byte" variables are different from "integer" variable with respect to automatic conversion to String.

My test code:

Private Sub toStringText
   Dim s As String 
   Dim b As Byte = 5
   Dim i As Integer = 6
   Dim ll As Long = 7
   Dim ib As Integer 
   
   debug.Print b         '  gives an unprintable character (ASCII code 5?)
   
   ib = b
   debug.Print ib
   
   s = b
   debug.Print s          '  gives an unprintable character (ASCII code 5?)
   
   s = i
   debug.Print s
   
   s = ll
   debug.Print s
End Sub

private static void toStringText() { Exception Err = null; Exception h2 = null;
    String s = "";
    byte b = (byte)5;
    int i = 6;
    long ll = 7;
    int ib = 0;

    Global.Debug().Print(String.valueOf(Conversion.CInt(b)));

    ib = Conversion.CInt(b);
    Global.Debug().Print(String.valueOf(ib));

    s = String.valueOf(Conversion.CInt(b));
    Global.Debug().Print(s);

    s = String.valueOf(i);
    Global.Debug().Print(s);

    s = String.valueOf(ll);
    Global.Debug().Print(s);
  }


My impression is that byte values are taken as ASCII character codes rather than as integer values.
In this respect, a byte is more a "char" than an "integer".
