property int NumberDecimalDigits { int get(); void set(int value); };public int NumberDecimalDigits { get; set; }member this.NumberDecimalDigits : int with get, setPublic Property NumberDecimalDigits As IntegerProperty Value
The number of decimal places to use in numeric values. The default for InvariantInfo is 2.
Exceptions

The property is being set and the NumberFormatInfo object is read-only.
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.
