' Example of the Decimal addition and subtraction operators.

Module Example

   Const dataFmt As String = "{0,-38}{1,31}"

   ' Display Decimal parameters and their sum and difference.
   Sub ShowDecimalSumDiff(ByVal outputBlock As System.Windows.Controls.TextBlock, ByVal Left As Decimal, ByVal Right As Decimal)

      outputBlock.Text &= vbCrLf
      outputBlock.Text += String.Format(dataFmt, "Decimal Left", Left) & vbCrLf
      outputBlock.Text += String.Format(dataFmt, "Decimal Right", Right) & vbCrLf

      ' The op_Addition and op_Subtraction operators must be
      ' explicitely coded in Visual Basic. If binary + or - are 
      ' used, other methods are called.
      outputBlock.Text += String.Format(dataFmt, _
          "Decimal.op_Addition( Left, Right )", _
          Decimal.op_Addition(Left, Right)) + vbCrLf
      outputBlock.Text += String.Format(dataFmt, _
          "Decimal.op_Subtraction( Left, Right )", _
          Decimal.op_Subtraction(Left, Right)) + vbCrLf

          "subtraction operators " & vbCrLf & "generates the " & _
          "following output. It displays the sum and " & vbCrLf & _
          "difference of several pairs of Decimal objects." + vbCrLf
