 | Flex 4.5(으)로 시작하는 경우 이 클래스 대신 spark.formatters.CurrencyFormatter 클래스를 사용하는 것이 좋습니다. |
The CurrencyFormatter class formats a valid number as a currency value. It adjusts the decimal rounding and precision, the thousands separator, and the negative sign; it also adds a currency symbol. You place the currency symbol on either the left or the right side of the value with the
alignSymbol property.
The currency symbol can contain multiple characters,
including blank spaces.
If an error occurs, an empty String is returned and a String that describes
the error is saved to the error property. The error
property can have one of the following values:
-
"Invalid value"means an invalid numeric value is passed to theformat()method. The value should be a valid number in the form of a Number or a String. -
"Invalid format"means one of the parameters contains an unusable setting.

alignSymbol | 속성 |
alignSymbol:String| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 3 |
| 런타임 버전: | Flash Player 9, AIR 1.1 |
Aligns currency symbol to the left side or the right side
of the formatted number.
Permitted values are "left" and "right".
기본값: "left".

currencySymbol:String| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 3 |
| 런타임 버전: | Flash Player 9, AIR 1.1 |
Character to use as a currency symbol for a formatted number. You can use one or more characters to represent the currency symbol; for example, "$" or "YEN". You can also use empty spaces to add space between the currency character and the formatted number. When the number is a negative value, the currency symbol appears between the number and the minus sign or parentheses.
기본값: "$".

Number of decimal places to include in the output String.
You can disable precision by setting it to -1.
A value of -1 means do not change the precision. For example,
if the input value is 1.453 and rounding
is set to NumberBaseRoundType.NONE, return 1.453.
If precision is -1 and you set some form of
rounding, return a value based on that rounding type.
기본값: -1.

In ActionScript, the value can be NumberBaseRoundType.NONE,
NumberBaseRoundType.UP,
NumberBaseRoundType.DOWN, or NumberBaseRoundType.NEAREST.
In MXML, the value can be "none",
"up", "down", or "nearest".
