flash actionscript: I would like to use the math round method, but am having some problems
with it. I have the following, and that goes into a text field to show
load progress:

var numPercentLoaded:Number = numBytesLoaded / numBytesTotal * 100;
numberLoaded_mc.numberBox = numPercentLoaded;

The problem is that the number has a bunch of decimal points that I
don't really want there. So I thought I could do something like this,
but that does seem to be wrong.

var numPercentLoaded:Number = numBytesLoaded / numBytesTotal * 100;
Math.round(numPercentLoaded);
numberLoaded_mc.numberBox = numPercentLoaded;

So I would like to round off the numPercentLoaded varible. What am I
doing wrong?

Thanks for any help!

Brian,

Ah, yup. I've done that, too. The problem here is that you're not
updating the value of your variable, you're simply invoking Math.round().
The Math.round() method returns a number, and you're not using that number.
This would work ...

var numPercentLoaded:Number = numBytesLoaded / numBytesTotal * 100;
numPercentLoaded = Math.round(numPercentLoaded);
numberLoaded_mc.numberBox = numPercentLoaded;

-- though, numberBox is the text field, right? So change that last line
from what it is to this:

numberLoaded_mc.numberBox.text = numPercentLoaded;

(you're updating the text property of the text field with the instance name
numberBox, I presume). Or, if you wanted to express the above three lines
more succinctly:

var numPercentLoaded:Number = numBytesLoaded / numBytesTotal * 100;
numberLoaded_mc.numberBox.text = Math.round(numPercentLoaded);
