Property Value

Int32

The number of decimal places to use in numeric values. The default for InvariantInfo is 2.

Exceptions

ArgumentOutOfRangeException

Examples

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

using namespace System;
using namespace System::Globalization;
int main()
{
   
   // Gets a NumberFormatInfo associated with the en-US culture.
   CultureInfo^ MyCI = gcnew CultureInfo( "en-US",false );
   NumberFormatInfo^ nfi = MyCI->NumberFormat;
   
   // Displays a negative value with the default number of decimal digits (2).
   Int64 myInt = -1234;
   Console::WriteLine( myInt.ToString( "N", nfi ) );
   
   // Displays the same value with four decimal digits.
   nfi->NumberDecimalDigits = 4;
   Console::WriteLine( myInt.ToString( "N", nfi ) );
}

/* 
This code produces the following output.
-1, 234.00
-1, 234.0000
*/

using System;
using System.Globalization;

class NumberFormatInfoSample {

   public static void Main() {

      // Gets a NumberFormatInfo associated with the en-US culture.
      NumberFormatInfo nfi = new CultureInfo( "en-US", false ).NumberFormat;

      // Displays a negative value with the default number of decimal digits (2).
      Int64 myInt = -1234;
      Console.WriteLine( myInt.ToString( "N", nfi ) );

      // Displays the same value with four decimal digits.
      nfi.NumberDecimalDigits = 4;
      Console.WriteLine( myInt.ToString( "N", nfi ) );
   }
}


/*
This code produces the following output.

-1,234.00
-1,234.0000
*/

Imports System.Globalization

Class NumberFormatInfoSample

   Public Shared Sub Main()

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

      ' Displays a negative value with the default number of decimal digits (2).
      Dim myInt As Int64 = - 1234
      Console.WriteLine(myInt.ToString("N", nfi))

      ' Displays the same value with four decimal digits.
      nfi.NumberDecimalDigits = 4
      Console.WriteLine(myInt.ToString("N", nfi))

   End Sub

End Class


'This code produces the following output.
'
'-1,234.00
'-1,234.0000

Remarks

The NumberDecimalDigits property is used with the "F" and "N" standard format strings without a precision specifier in numeric formatting operations. It defines the default number of fractional digits that appear after the decimal separator. This value is overridden if a precision specifier is used. For more information, see Standard Numeric Format Strings.
