Eww.
That is so hard to read.
Either use a labelFunction or just fix PrepForDisplay.format().

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
I don't recommend writing complicated binding expressions, because you
have to use lt; in place of , gt; in place of , and amp; in place
of .

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
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
Hi Sid, thanks a lot for your help. I figured it out! Really just need a
starting point for where to look. Cheers!

Just one more question. The zero works for me, but I¹m sure I¹ll be asked to
make it blank. Any hints as to how this could be accomplished? Coming from
the Flash side of things, all I would be looking to do is change the alpha
value of the label to zero if the value was 0.

How about:
sNaN(mynumber) ? 0 :

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
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
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
