Examples
The following example demonstrates the effect of changing the PercentDecimalDigits 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).
Double myInt = 0.1234;
Console::WriteLine( myInt.ToString( "P", nfi ) );
// Displays the same value with four decimal digits.
nfi->PercentDecimalDigits = 4;
Console::WriteLine( myInt.ToString( "P", nfi ) );
}
/*
This code produces the following output.
12.34 %
12.3400 %
*/
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).
Double myInt = 0.1234;
Console.WriteLine( myInt.ToString( "P", nfi ) );
// Displays the same value with four decimal digits.
nfi.PercentDecimalDigits = 4;
Console.WriteLine( myInt.ToString( "P", nfi ) );
}
}
/*
This code produces the following output.
12.34 %
12.3400 %
*/

Remarks
The PercentDecimalDigits property is used with the "P" standard format string 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.
