Justin Mclean commented on FLEX-26698:
--------------------------------------

Issue still exists and interestingly enough the spark formatter also gets it 
wrong (in another way).

                ]]>
        </fx:Script>

</s:Application>

Output of above:
mx.formatters.CurrencyFormatter
0 = $.0
1 = $1
spark.formatters.CurrencyFormatter
0 = 0
1 = USD1.00
flash.globalization.CurrencyFormatter
0 = 0
1 = USD1.00

Should be easy to fix if anyone wants to try.

>             Project: Apache Flex
>          Issue Type: Bug
>          Components: Formatters
>    Affects Versions: Adobe Flex SDK Previous
>         Environment: Affected OS(s): All OS Platforms
> Affected OS(s): All OS Platforms
> Language Found: English
>            Reporter: Adobe JIRA
>              Labels: easyfix
>
> Steps to reproduce:
> 1. Create a CurrecyFormatter instance
> 2. Use default configuration
> 3. Attempt to format the value 0.
> Code Example:
> var formatter:CurrencyFormatter = new CurrencyFormatter();
> var value:String = formatter.format(0);
>  
>  Actual Results:
> value will be equal to '$.0'
>  
>  Expected Results:
> '$0'
>  
>  
>  Workaround (if any):
>  
>  Do a secondary check for a value equal to zero in your logic prior to 
> calling the formatter.
