int,
uint, and Number objects.
This class is a wrapper class around the flash.globalization.NumberFormatter class. Therefore, the locale-specific formatting is provided by the flash.globalization.NumberFormatter. However, this NumberFormatter class can be used in MXML declarations, uses the locale style for the requested Locale ID name, and has methods and properties that are bindable.
The flash.globalization.NumberFormatter class use the underlying operating system for the formatting functionality and to supply the locale-specific data. On some operating systems, the flash.globalization classes are unsupported, on these systems this wrapper class provides fallback functionality.

The name of the actual locale ID used by this class object. This is the locale that is used to access the formatting data and functionality from the operating system.
If the locale that was set by the locale style is not available,
then the value of the actualLocaleIDName is different
from the value of the locale style.
It indicates the fallback locale that is being used.
If the locale style was set to LocaleID.DEFAULT the
name of the locale specified by the user's operating system is
used.

A numeric value that indicates a formatting pattern for negative numbers. This pattern defines the location of the negative symbol or parentheses in relation to the numeric portion of the formatted number.
The following table summarizes the possible formats for
negative numbers. When a negative number is formatted,
the minus sign in the format is replaced with the value of
the negativeSymbol property and the 'n' character is
replaced with the formatted numeric value.
| Negative number format type | Format |
| 0 | (n) |
| 1 | -n |
| 2 | - n |
| 3 | n- |
| 4 | n - |
The default value is dependent on the locale and operating system.

public function NumberFormatter()| Dil Sürümü: | ActionScript 3.0 |
| Ürün Sürümü: | Flex 4.5 |
| Çalışma Zamanı Sürümleri: | Flash Player 10.1, AIR 2.5 |
Constructs a new NumberFormatter object to format numbers according to the conventions of a given locale.
The locale for this class is supplied by the locale style. The locale style can be set in several ways:
-
By using the class in an MXML declaration and inheriting the
locale from the document that contains the declaration.
Example:
<fx:Declarations> <s:NumberFormatter id="nf" /> </fx:Declarations> -
By using an MXML declaration and specifying the locale value in
the list of assignments.
Example:
<fx:Declarations> <s:NumberFormatter id="nf_French_France" locale="fr_FR" /> </fx:Declarations> -
Calling the setStyle method. For example:
nf.setStyle("locale", "fr-FR") -
Inheriting the style from a
UIComponentby calling the UIComponent'saddStyleClient()method.
If the locale style is not set by one of the above
techniques, the instance of this class will be added as a
StyleClient to the topLevelApplication and
will therefore inherit the locale style from the
topLevelApplication object when the locale
dependent property getter or locale dependent method is
called.
Most of the properties of this class are automatically set based on the locale style. If the locale style is changed, any properties that have not been explicitly set will also be updated based on the new locale. Note that the actual locale that is used is specified by the actualLocaleIDName property.

Formats a number.
This function formats the number based on the property values
of the formatter.
If the properties are not modified after the locale style is set,
the numbers are formatted according to the locale-specific conventions
provided by the operating system for the locale identified
by the actualLocaleIDName property.
To customize the format, the properties
can be altered to control specific aspects of formatting a number.
Very large numbers and very small magnitude numbers can be
formatted with this function. However, the
number of significant digits is limited to the precision provided
by the Number object. Scientific notation is not
supported.
If there is an error when formatting, due to an illegal input value
or other error, by default the format() method
returns null.
However if the errorText property
is non-null, then the value of the errorText property
is returned. The lastOperationStatus property will be
set to indicate the error that occurred.
Parametreler
value:Object — An object containing a number value to format. If the
object is not a Number then it is converted
to a number using the Number() conversion function.
|
String — A formatted number string.

Lists all of the locale ID names supported by this class. This is a list of locales supported by the operating system, not a list of locales that the ResourceManager has resources for.

| Ürün Sürümü: | Flex 4.5 |
| Çalışma Zamanı Sürümleri: | Flash Player 10.1, AIR 2.5 |
Parses a string and returns a NumberParseResult object
containing the parsed elements.
The NumberParseResult object contains
the value of the first number found in the input string, the
starting index for the number within the string, and the index
of the first character after the number in the string.
If the string does not contain a number, the value property of
the NumberParseResult is set to NaN and the
startIndex and endIndex properties are
set to the hexadecimal value 0x7fffffff.
This function uses the value of the decimalSeparator
property to determine the portion of the number
that contains fractional
digits, and the groupingSeparator property to determine
which characters are allowed within the digits of a number,
and the negativeNumberFormat property to control
how negative values are represented.
The following table identifies the result of strings parsed
for the various NegativeNumberFormat values:
| NegativeNumberFormat | Input String | Result |
| (n) | "(123)" or "( 123 )" | "-123" |
| -n | "-123" or "- 123" | "-123" |
| - n | "-123" or "- 123" | "-123" |
| n- | "123-" or "123 -" | "-123" |
| n - | "123-" or "123 -" | "-123" |
A single white space is allowed between the number and the minus sign or parenthesis. A white space character is a character that has a Space Separator (Zs) property in the Unicode Character Database. For more information, see http://www.unicode.org/ucd/).
Other properties are ignored when determining a valid number.
Specifically the value of the
digitsType property is ignored and the digits can be
from any of
the digit sets that are enumerated in the
NationalDigitsType class.
The values of the groupingPattern
and useGrouping properties do not influence the
parsing of the number.
If numbers are preceded or followed in the string by a plus sign '+', the plus sign is treated as a character that is not part of the number.
This function does not parse strings containing numbers in scientific notation (e.g. 1.23e40).
Parametreler
inputString:String — The input string to parse.
|
NumberParseResult — A NumberParseResult object containing the numeric
value and the indices for the start and end of the portion of the string
that contains the number.
|
Atar
TypeError — if the inputString parameter is null.

Parses a string that contains only digits and optional whitespace
characters and returns a Number. If the string does not begin
with a number or contains characters other than whitespace that
are not part of the number, then this method returns
NaN. White space before or after
the numeric digits is ignored.
If the numeric digit is preceded or followed by a
plus sign '+' it is treated as a non-whitespace character.
The return value is NaN.
See the description of the parse function for more information about number parsing and what constitutes a valid number.
