Examples

The following example demonstrates the effect of changing the CurrencyDecimalDigits property.

Imports System.Globalization

Class Example

   Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)

      ' Gets a NumberFormatInfo associated with the en-US culture.
      Dim nfi As NumberFormatInfo = New CultureInfo("en-US").NumberFormat

      ' Displays a negative value with the default number of decimal digits (2).
      Dim myInt As Int64 = -1234
      outputBlock.Text += String.Format(myInt.ToString("C", nfi)) & vbCrLf

      ' Displays the same value with four decimal digits.
      nfi.CurrencyDecimalDigits = 4
      outputBlock.Text += String.Format(myInt.ToString("C", nfi)) & vbCrLf

   End Sub 'Main 

End Class 'NumberFormatInfoSample
