The maximum number of digits that can appear after the decimal separator.
Numbers are rounded to the number of digits specified by this property. The rounding scheme varies depending on the application user's operating system.
When the trailingZeros property is set to
true, the fractional portion of the
number (after the decimal separator) is padded with trailing zeros
until its length matches the value of this
fractionalDigits property.

groupingPattern | proprietà |
groupingPattern:String| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 4.5 |
| Versioni runtime: | Flash Player 10, AIR 2.5 |
Describes the placement of grouping separators within the formatted number string.
When the useGrouping property is set to true,
the groupingPattern property is used
to define the placement and pattern used for the grouping
separator.
The grouping pattern is defined as a string containing
numbers separated by semicolons and optionally may end
with an asterisk. For example: "3;2;*".
Each number in the string represents the number of digits
in a group. The grouping separator is placed before each
group of digits. An asterisk at the end of the string
indicates that groups with that number of digits should be
repeated for the rest of the formatted string.
If there is no asterisk then there are no additional groups
or separators for the rest of the formatted string.
The first number in the string corresponds to the first
group of digits to the left of the decimal separator.
Subsequent numbers define the number of digits in subsequent
groups to the left. Thus the string "3;2;*"
indicates that a grouping separator is placed after the first
group of 3 digits, followed by groups of 2 digits.
For example: 98,76,54,321
The following table shows examples of formatting the number 123456789.12 with various grouping patterns. The grouping separator is a comma and the decimal separator is a period.
| Grouping Pattern | Sample Format |
3;* | 123,456,789.12 |
3;2;* | 12,34,56,789.12 |
3 | 123456,789.12 |
Only a limited number of grouping sizes can be defined.
On some operating systems, grouping patterns can only contain
two numbers plus an asterisk. Other operating systems can
support up to four numbers and an asterisk.
For patterns without an asterisk, some operating systems
only support one number while others support up to three numbers.
If the maximum number of grouping pattern elements is exceeded,
then additional elements
are ignored and the lastOperationStatus property
is set to indicate that a fall back value is
being used.
The default value is dependent on the locale and operating system.

groupingSeparator:String| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 4.5 |
| Versioni runtime: | Flash Player 10, AIR 2.5 |
The character or string used for the grouping separator.
The value of this property is used as the grouping
separator when formatting numbers with the
useGrouping property set to true. This
property is initially set based on the locale that is selected
when the formatter object is constructed.
The default value is dependent on the locale and operating system.

lastOperationStatus:String [sola lettura] [override] | Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 4.5 |
| Versioni runtime: | Flash Player 10, AIR 2.5 |
The status of the most recent operation that this class object
performed.
The lastOperationStatus is set whenever the constructor
or a method of this class is called, or when a property is set.
For the possible values see the description under each method.

leadingZero:Boolean| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 4.5 |
| Versioni runtime: | Flash Player 10, AIR 2.5 |
Specifies whether a leading zero is included in a formatted number when there are no integer digits to the left of the decimal separator.
When this property is set to true a leading
zero is included to the left of the decimal separator
when formatting numeric values between -1.0 and 1.0.
When this property is set to false, a leading zero
is not included.
For example, if the number is 0.321 and this property is
set true, then the leading
zero is included in the formatted string. If the property is
set to false, the leading zero
is not included. In that case the string would just include the
decimal separator followed by the decimal digits,
such as .321.
The following table shows examples of how numbers are formatted
based on the values of this property and
the related fractionalDigits and
trailingZeros properties.
| trailingZeros | leadingZero | fractionalDigits | 0.12 | 0 |
| true | true | 3 | 0.120 | 0.000 |
| false | true | 3 | 0.12 | 0 |
| true | false | 3 | .120 | .000 |
| false | false | 3 | .12 | 0 |

negativeSymbol | proprietà |
negativeSymbol:String| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 4.5 |
| Versioni runtime: | Flash Player 10, AIR 2.5 |
The negative symbol to be used when formatting negative values.
This symbol is used with the negative number format when formatting a number that is less than zero. It is not used in negative number formats that do not include a negative sign (e.g. when negative numbers are enclosed in parentheses).
This property is set to a default value for the actual locale selected when this formatter is constructed. It can be set with a value to override the default setting.
The default value is dependent on the locale and operating system.

trailingZeros | proprietà |
trailingZeros:Boolean| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 4.5 |
| Versioni runtime: | Flash Player 10, AIR 2.5 |
Specifies whether trailing zeros are included in a formatted number.
When this property is set to true, trailing
zeros are included in the fractional part
of the formatted number up to the limit specified by the
fractionalDigits property.
When this property is set to false then no
trailing zeros are shown.
For example, if the numeric value is 123.4, and this property
is set true, and the fractionalDigits property
is set to 3, the formatted string would show trailing zeros,
such as 123.400 .
If this property is false, trailing zeros are not
included, and the string shows just the decimal
separator followed by the non-zero decimal digits, such as
123.4.
The following table shows examples of how numeric values are
formatted based on the values of this property and
the related fractionalDigits and
leadingZero properties.
| trailingZeros | leadingZero | fractionalDigits | 0.12 | 0 |
| true | true | 3 | 0.120 | 0.000 |
| false | true | 3 | 0.12 | 0 |
| true | false | 3 | .120 | .000 |
| false | false | 3 | .12 | 0 |

| Versione prodotto: | Flex 4.5 |
| Versioni runtime: | Flash Player 10, AIR 2.5 |
Enables the use of the grouping separator when formatting numbers.
When the useGrouping property is set to
true, digits are grouped and
delimited by the grouping separator character.
For example: 123,456,789.22
When the useGrouping property is set to
false, digits are not grouped or separated.
For example: 123456789.22
The symbol to be used as a grouping separator is defined
by the groupingSeparator property. The number of digits
between grouping separators is defined by the
groupingPattern property.
The default value is dependent on the locale and operating system.
