NumberFormatInfo::NumberDecimalDigits Property

Gets or sets the number of decimal places to use in numeric values.

Namespace:  System.Globalization
Assembly:  mscorlib (in mscorlib.dll)

public:
property int NumberDecimalDigits {
	int get ();
	void set (int value);
}

Property Value

Type: System::Int32
The number of decimal places to use in numeric values. The default for InvariantInfo is 2.

ExceptionCondition
ArgumentOutOfRangeException

The property is being set to a value that is less than 0 or greater than 99.

InvalidOperationException

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

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.

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 ) );
}
