Public Overridable Property NumberFormat As NumberFormatInfo
A NumberFormatInfo that defines the culturally appropriate format of displaying numbers, currency, and percentage.
The property is set to null.
The NumberFormat property or any of the NumberFormatInfo properties is set, and the CultureInfo is read-only.
The following code example shows that CultureInfo.Clone also clones the DateTimeFormatInfo and NumberFormatInfo instances associated with the CultureInfo.
using namespace System;
using namespace System::Globalization;
int main()
{
// Creates and initializes a CultureInfo.
CultureInfo^ myCI = gcnew CultureInfo( "en-US",false );
// Clones myCI and modifies the DTFI and NFI instances associated with the clone.
CultureInfo^ myCIclone = dynamic_cast<CultureInfo^>(myCI->Clone());
myCIclone->DateTimeFormat->AMDesignator = "a.m.";
myCIclone->DateTimeFormat->DateSeparator = "-";
myCIclone->NumberFormat->CurrencySymbol = "USD";
myCIclone->NumberFormat->NumberDecimalDigits = 4;
// Displays the properties of the DTFI and NFI instances associated with the original and with the clone.
Console::WriteLine( "DTFI/NFI PROPERTY\tORIGINAL\tMODIFIED CLONE" );
Console::WriteLine( "DTFI.AMDesignator\t{0}\t\t{1}", myCI->DateTimeFormat->AMDesignator, myCIclone->DateTimeFormat->AMDesignator );
Console::WriteLine( "DTFI.DateSeparator\t{0}\t\t{1}", myCI->DateTimeFormat->DateSeparator, myCIclone->DateTimeFormat->DateSeparator );
Console::WriteLine( "NFI.CurrencySymbol\t{0}\t\t{1}", myCI->NumberFormat->CurrencySymbol, myCIclone->NumberFormat->CurrencySymbol );
Console::WriteLine( "NFI.NumberDecimalDigits\t{0}\t\t{1}", myCI->NumberFormat->NumberDecimalDigits, myCIclone->NumberFormat->NumberDecimalDigits );
}

You might choose to override some of the values associated with the current culture of Windows through the regional and language options portion of Control Panel. For example, the user might choose to display the date in a different format or to use a currency other than the default for the culture.
If UseUserOverride is true
and the specified culture matches the current culture of Windows, the CultureInfo uses those overrides, including user settings for the properties of the DateTimeFormatInfo instance returned by the DateTimeFormat property, and the properties of the NumberFormatInfo instance returned by the NumberFormat property. If the user settings are incompatible with the culture associated with the CultureInfo, for example, if the selected calendar is not one of the OptionalCalendars, the results of the methods and the values of the properties are undefined.
The values of the DateTimeFormat property and the NumberFormat property are not calculated until the user accesses the property. If the user uses the Control Panel to change the current culture to a new culture while the application is running and then accesses the DateTimeFormat or NumberFormat property, the application retrieves the defaults for the new culture. not the overrides for the original culture. To preserve the overrides for the original current culture, the application should access the DateTimeFormat and NumberFormat properties before changing the current culture.
