 | Flex 4.5(으)로 시작하는 경우 이 클래스 대신 spark.formatters.NumberFormatter 클래스를 사용하는 것이 좋습니다. |
The NumberFormatter class formats a valid number by adjusting the decimal rounding and precision, the thousands separator, and the negative sign.
If you use both the rounding and precision
properties, rounding is applied first, and then you set the decimal length
by using the specified precision value.
This lets you round a number and still have a trailing decimal;
for example, 303.99 = 304.00.
If an error occurs, an empty String is returned and a String
describing 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 contain an unusable setting.

decimalSeparatorFrom | 속성 |
decimalSeparatorFrom:String| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 3 |
| 런타임 버전: | Flash Player 9, AIR 1.1 |
Decimal separator character to use when parsing an input String.
When setting this property, ensure that the value of the
thousandsSeparatorFrom property does not equal this property.
Otherwise, an error occurs when formatting the value.
기본값: ".".

decimalSeparatorTo | 속성 |
decimalSeparatorTo:String| 언어 버전: | ActionScript 3.0 |

Decimal separator character to use when outputting formatted decimal numbers.
When setting this property, ensure that the value of the
thousandsSeparatorTo property does not equal this property.
Otherwise, an error occurs when formatting the value.
기본값: ".".

precision | 속성 |
precision:Object| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 3 |
| 런타임 버전: | Flash Player 9, AIR 1.1 |
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 a value of 1.453.
If precision is -1 and you have set some form of
rounding, return a value based on that rounding type.
기본값: -1.

rounding:String| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 3 |
| 런타임 버전: | Flash Player 9, AIR 1.1 |
Specifies how to round the number.
In ActionScript, you can use the following constants to set this property:
NumberBaseRoundType.NONE, NumberBaseRoundType.UP,
NumberBaseRoundType.DOWN, or NumberBaseRoundType.NEAREST.
Valid MXML values are "down", "nearest", "up", and "none".
기본값: NumberBaseRoundType.NONE.
