Re: [flexcoders] NaN and Infinity showing in output - How to modify?
Eww, eh? Well, gee, Tom, I hope I didn't spoil your breakfast or anything ;)
I think both your refactorings are good ones. I was definitely in how do we
get this working mode, not how do we get this as elegantly written as
possible mode: i.e. I was in code-writing not refactoring mode. So I suppose I
shouldn't complain about you pointing out a bad smell coming from the code
writing.
Having said that, I have to admit that I am not at all clear as to protocol for
how much ActionScript is acceptable within braces while assigning to an MXML
attribute, or whether there are accepted standards for this. I have the fear
that this might be a religious question, but maybe not. If there are accepted
protocols, I'd love to hear what they are.
Just to help clarify things, I'm wondering whether you have any objection to
ternary statements, or if you do just feel that this is too much code to have
within an attribute assignment. For example, would this satisfy your objection:
mx:Script
![CDATA[
private function formatLabel():String {
private var result:String;
result = (isNaN(myNumber as Number)) ? 0 :
PrepForDisplay.format(myNumber);
return result;
}
]]
/mx:Script
mx:Label id=display text={formatLabel()} /

Re: [flexcoders] NaN and Infinity showing in output - How to modify?
If the format function is a custom function you have written, you could just
have it check whether you like the result it is about to return, and if not,
return something else. If that is not the case, I believe that you should be
able to put tests into your binding statement.
You could test for NaN with something like this:
mx:Label text={(myNumber is NaN) ? 0 : PrepForDispl ay.format( myNumber) }/
I'm not sure about infinity, but I assume that you can test for this by looking
for the greatest possible value of the number. Assuming that you have set up
the variable maxValue to contain that value, you should be able to do something
like this:
mx:Label text={(myNumber maxValue) ? 0 : PrepForDispl ay.format( myNumber)
}/
If you put the two together, it would look something like this:
mx:Label text={(myNumber is NaN) ? 0 : (myNumber maxValue) ? 0 :
PrepForDispl ay.format( myNumber) }/

Subject: [flexcoders] NaN and Infinity showing in output - How to modify?
I seem to have trouble explaining myself here, hard when you are just
learning. Perhaps this will be better.
Is it possible to remove, change or hide any label or text output that
displays NaN or Infinity?
I'm performing a very simply calculation where the user enters a
number in a form and it is calculated and displayed. Simple and does
what I need. In some instances, there are more variables required and
until they are provided, the output display NaN or Infinity.
How could I easily adjust these? It could be a default display of
zero, it could be to display nothing, whatever is the easiest and most
straight forward method.
Below is only an example of how I'm taking the user input from the
form and passing the variable on to the Label text output.
mx:Number id=myNumber {Number( userInput. text) * (1 +
Number(otherUserInp ut.text)) * 1 /
Number(otherOtherUs erInput.text) }/mx:Number
The answer is output to:
mx:Label text={PrepForDispl ay.format( myNumber) }/
Thank you, any assistance you can provide would be welcomed.
Re: [flexcoders] NaN and Infinity showing in output - How to modify?
Hi Sid, thanks for the reply. I tried your first solution since I did not
create a custom function and it returns;
1067: Implicit coercion of value of type Number to an unrelated type Class
I have a vague understanding of what is occurring here. Any way around it?
How difficult would it be to modify or create a custom function?
What I have now is simply:
mx:NumberFormatter id=PrepForDisplayprecision=2
rounding=updecimalSeparatorTo=.thousandsSeparatorTo=,
useThousandsSeparator=trueuseNegativeSign=true/

Re: [flexcoders] NaN and Infinity showing in output - How to modify?
Try something like this:
mx:Label id=display text={(isNaN(myNumber as Number)) ? 0 :
PrepForDisplay.format(myNumber)} visible={display.text != '0' amp;amp;
display.text != 'In,fin,ity.00'}/
Note that you need to give the Label component and id, and use that id to refer
to it in your statements within braces.
By the way, as you are no doubt noticing, the larger point here is that braces
are not just for binding, but can contain all sorts of ActionScript.
Finally, the reason that there is amp;amp; instead of is that we are
inside of MXML, which is to say inside of XML, and we cannot use the
character there, but must escape it.

Re: [flexcoders] NaN and Infinity showing in output - How to modify?
Actually, if you are just going to hide the label field, you can just have it
display the result of the formatting, and put the checking for NaN and infinity
into the setting for visibility. Since you are going to hide the label and it
has a value you don't like, you don't really care what it is displaying when it
is invisible.

Re: [flexcoders] NaN and Infinity showing in output - How to modify?
Hmm, sorry the last post left a part out, it was shown lower down:
mx:Label ... text={isNaN(mynumber) ? 0 : PrepForDisplay.format(mynumber)}
... /
Adding the ³² as you stated, returns an error for mx:Label, ³² or ³/².
The zero is what is display in the application, if I could provide a short
string instead, it would be ideal. Even if the initial default text of the
label was ³whatever² until a calculated value was entered. But there are
many, many of these calculations to perform and I would like to find the
simplest answer. Close though, thanks for the help.

Subject: Re: [flexcoders] NaN and Infinity showing in output - How to
modify?
If the format function is a custom function you have written, you could just
have it check whether you like the result it is about to return, and if not,
return something else. If that is not the case, I believe that you should be
able to put tests into your binding statement.
You could test for NaN with something like this:
mx:Label text={(myNumber is NaN) ? 0 : PrepForDispl ay.format( myNumber)
}/
I'm not sure about infinity, but I assume that you can test for this by
looking for the greatest possible value of the number. Assuming that you
have set up the variable maxValue to contain that value, you should be able
to do something like this:
mx:Label text={(myNumber maxValue) ? 0 : PrepForDispl ay.format(
myNumber) }/
If you put the two together, it would look something like this:
mx:Label text={(myNumber is NaN) ? 0 : (myNumber maxValue) ? 0 :
PrepForDispl ay.format( myNumber) }/
