Remarks

If your app passes language tags used in this class to any National Language Support functions, it must first convert the tags by calling ResolveLocaleName.

Constructors

DecimalFormatter() DecimalFormatter() DecimalFormatter()

Creates a DecimalFormatter object and initializes it to default values.

public DecimalFormatter()public DecimalFormatter()Public Sub New()
Attributes

DecimalFormatter(IIterable<String>, String) DecimalFormatter(IIterable<String>, String) DecimalFormatter(IIterable<String>, String)

Creates a DecimalFormatter object initialized by a language list and a geographic region.

public DecimalFormatter(IIterable<String> languages, String geographicRegion)public DecimalFormatter(IIterable<String> languages, String geographicRegion)Public Sub New(languages As IIterable<String>, geographicRegion As String)
Parameters
languages

The list of language identifiers, in priority order, representing the choice of languages. See Remarks.

geographicRegion
System.String System.String System.String

The identifier for the geographic region.

Attributes

Remarks

If your app passes language tags used in this class to any National Language Support functions, it must first convert the tags by calling ResolveLocaleName.

Starting in : Language tags support the Unicode extensions "ca-" and "nu-". (See Unicode Key/Type Definitions.) Note that the "nu-" extension can affect the numeral system used by DecimalFormatter objects.

Attributes

GeographicRegion GeographicRegion GeographicRegion

Gets the region that is used when formatting and parsing decimal numbers.

public PlatForm::String GeographicRegion { get; }public string GeographicRegion { get; }Public ReadOnly Property GeographicRegion As string
Value
string string string

The region that is used.

Attributes

IntegerDigits IntegerDigits IntegerDigits

Gets or sets the minimum number of digits to display for the integer part of the number.

public int IntegerDigits { get; set; }public int IntegerDigits { get; set; }Public ReadWrite Property IntegerDigits As int
Value
int int int

The minimum number of digits to display.

Attributes

IsDecimalPointAlwaysDisplayed IsDecimalPointAlwaysDisplayed IsDecimalPointAlwaysDisplayed

Gets or sets whether the decimal point of the number should always be displayed.

public PlatForm::Boolean IsDecimalPointAlwaysDisplayed { get; set; }public bool IsDecimalPointAlwaysDisplayed { get; set; }Public ReadWrite Property IsDecimalPointAlwaysDisplayed As bool
Value
bool bool bool

True if the decimal point of the number should always be displayed, and false otherwise.

Attributes

IsGrouped IsGrouped IsGrouped

Gets or sets whether the integer part of the number should be grouped.

public PlatForm::Boolean IsGrouped { get; set; }public bool IsGrouped { get; set; }Public ReadWrite Property IsGrouped As bool
Value
bool bool bool

True if the integer part of the number should be grouped, and false otherwise.

Attributes

IsZeroSigned IsZeroSigned IsZeroSigned

Gets or sets whether -0 is formatted as "-0" or "0".

public PlatForm::Boolean IsZeroSigned { get; set; }public bool IsZeroSigned { get; set; }Public ReadWrite Property IsZeroSigned As bool
Value
bool bool bool

True if -0 is formatted as "-0", and false if -0 is formatted as "0".

Attributes

Remarks

You can set this property to specify that DecimalFormatter display negative 0 as "-0". This enables the scenario where you wish to display "-0" when it represents the rounded value of some small negative value (such as -0.00001).

This property defaults to false to be consistent with Windows 8 and Windows Server 2012, in which -0 was always formatted as "0".

public IVectorView<string> Languages { get; }public IVectorView<string> Languages { get; }Public ReadOnly Property Languages As IVectorView<string>
Value

The priority list of language identifiers.

Starting in : Language tags can support Unicode extensions. See the Remarks for the DecimalFormatter(IIterable(String), String) constructor.

Attributes

Remarks

If your app passes language tags from this class to any National Language Support functions, it must first convert the tags by calling ResolveLocaleName.

Gets or sets the current rounding strategy to be used when formatting numbers.

public INumberRounder NumberRounder { get; set; }public INumberRounder NumberRounder { get; set; }Public ReadWrite Property NumberRounder As INumberRounder
Attributes

Remarks

When a Format method is called, the appropriate rounding function from the number rounder object manipulates the input prior to it being formatted.

NumeralSystem NumeralSystem NumeralSystem

Gets or sets the numbering system that is used to format and parse decimal numbers.

public PlatForm::String NumeralSystem { get; set; }public string NumeralSystem { get; set; }Public ReadWrite Property NumeralSystem As string
Value
string string string

A string that indicates the numeral system of the formatter, such as "Latn" for the Latin numeral system (0123456789) or "Arab" for the Arabic-Indic numeral system (٠١٢٣٤٥٦٧٨٩). See the supported NumeralSystem values.
