The JavaScript and ActionScript codes are not doing exactly the same
thing. In your AS code, at a certain point you are doing the following
assignment:
_testValue = qualifier.toLowerCase()+ ",$";
This will result in _testValue = "true,$" which will make the test
isCurrency.test(_testValue) return false which is right because
isCurrency's regex is /^, ?\$/.
