[Flashcoders] [AS in general] Question corcerning a math formula
Goodmorning, i am trying to make a formula that makes for example 30.60 of 30.6. So I need it to add a 0. This is the formula I am using now. total = Number(Number(600) / 100 * Number(5.1)) I have tried all sorts of additions to the formula to try to get it to make 30.60 of 30.6. But no luck Anyone here who knows how to make the formula add a 0?

Re: [Flashcoders] [AS in general] Question corcerning a math formula
Hi Jim, In the Number class there is are a couple of functions to help you. You want a function called toFixed(). so if you do Number(total).toFixed(2); You get the result you want :) This is pure AS3 though, Hope this helps, Sid On Jan 27, 2009, at 9:45 AM, jimmi wrote: Goodmorning, i am trying to make a formula that makes for example 30.60 of 30.6.

Re: [Flashcoders] [AS in general] Question corcerning a math formula
you need to add it to a string and work out if the extra 0 is needed (maybe with the modulo (%) comparison operator), in as2, and then manually add the zero to the string when you output to your textfield do a search for as2 timers / digital clocks and you'll come across the technique a On Tue, Jan 27, 2009 at 9:05 AM, jimmi cho...@gmail.com wrote: Ah snap, i need it for AS2, is there any alternative for that?

Re: [Flashcoders] [AS in general] Question corcerning a math formula
Hi Jimmi,
Look at this then,
To truncate Numbers in Actionscript:
Three decimals:
var yourNumber:Number = 23.263636453737383838383838;
yourNumber = Math.round(yourNumber *1000)/1000;
// Outputs 23.263
Two decimals:
var yourNumber:Number = 23.263636453737383838383838;
yourNumber = Math.round(yourNumber *100)/100;
// Outputs 23.26
One decimal:
var yourNumber:Number = 23.263636453737383838383838;
yourNumber = Math.round(yourNumber *10)/10;
// Outputs 23.2
and if you want to do it even nicer you do it like this:
function round(number:Number, precision:Number):Number
{
var decimalPlaces:Number = Math.pow(10, precision);
trace(Math.round(decimalPlaces * number) / decimalPlaces)
return Math.round(decimalPlaces * number) / decimalPlaces;
}
round(2.5678, 2);
Hope this helps,

Re: [Flashcoders] [AS in general] Question corcerning a math formula
Oh Allandt i misread, sorry.
Yes flash does remove the zero at the end of decimal values.
But then you only want to use this function to display (in a textfield
or something) and not to calcualte with it,
because calculating with double zeroes is the same calucalting with a
zero :) ie 4 * 2.0 == 4 *2.
To fix it do this (AS3 code):
function round(pValue:Number, precision:int):String {
var intVal:Number = Math.floor(pValue);
var finalLength : int = intVal.toString().length + 1 + precision;
var baseString : String = pValue.toString().substr(0, finalLength);
if(baseString.length == intVal.toString().length) {
baseString += .;
}
while(baseString.length finalLength) {
baseString += 0;
}
return baseString;
}
If there is someone on this list who would like to convert this
function to AS2 to help Jimmi that would be awesome :)
Cheers,
Sid

Hi Jim,
In the Number class there is are a couple of functions to help you. You
want
a function called toFixed().
so if you do Number(total).toFixed(2); You get the result you want :)
This is pure AS3 though,
Hope this helps,

This is the formula I am using now.

I have tried all sorts of additions to the formula to try to get it to
make 30.60 of 30.6. But no luck
Anyone here who knows how to make the formula add a 0?

Re: [Flashcoders] [AS in general] Question corcerning a math formula
If it works, it works :)
Try converting it to a function so you can reuse it later.
Happy coding :)

Oh Allandt i misread, sorry.
Yes flash does remove the zero at the end of decimal values.
But then you only want to use this function to display (in a
textfield or
something) and not to calcualte with it,
because calculating with double zeroes is the same calucalting with
a zero
:) ie 4 * 2.0 == 4 *2.
To fix it do this (AS3 code):
function round(pValue:Number, precision:int):String {
var intVal:Number = Math.floor(pValue);
var finalLength : int = intVal.toString().length + 1 +
precision;
var baseString : String = pValue.toString().substr(0,
finalLength);
if(baseString.length == intVal.toString().length) {
baseString += .;
}
while(baseString.length finalLength) {
baseString += 0;
}
return baseString;
}
If there is someone on this list who would like to convert this
function to
AS2 to help Jimmi that would be awesome :)

Hi Jimmi,
Look at this then,
To truncate Numbers in Actionscript:
Three decimals:
var yourNumber:Number = 23.263636453737383838383838;
yourNumber = Math.round(yourNumber *1000)/1000;
// Outputs 23.263
Two decimals:
var yourNumber:Number = 23.263636453737383838383838;
yourNumber = Math.round(yourNumber *100)/100;
// Outputs 23.26
One decimal:
var yourNumber:Number = 23.263636453737383838383838;
yourNumber = Math.round(yourNumber *10)/10;
// Outputs 23.2
and if you want to do it even nicer you do it like this:
function round(number:Number, precision:Number):Number
{
var decimalPlaces:Number = Math.pow(10, precision);
trace(Math.round(decimalPlaces * number) / decimalPlaces)
return Math.round(decimalPlaces * number) / decimalPlaces;
}
round(2.5678, 2);

Hi,
I think if you use it locally, you still have to dispose of it:

http://labs.bigspaceship.com/2007/02/28/flash-performance-tips-part-ii/

Search for dispose in some of these - also, one of the comments in
Grant's article mentions testing in the IDE vs testing in the browser
gives different results for loaded images.

Hi cool list,
I'm struggling with my Image class. It's supposed to load and unload
different sized images dynamicly; but I can't seem to get it to work
properly. The loading works fine, but the unloading not for the full 100%.
It visually unloads the image, but it remains in the memory. I have tried
several different things; I'm a bit stuck now.
Here is a stripped class:
public class Image extends MovieClip

[Flashcoders] instancing my own components (still new to AS3)
Hi list...
What exactly is the AS3 equivalent of making a simple component,
creating a component definition, and attachMovie with the {} holding the
params?
I can't get this to work:
package {
import flash.display.MovieClip;
import flash.text.*;
public class MyButton extends MovieClip{
public var buttonLabel:String;
public function MyButton (buttonLabel:String){
this.buttonLabel = buttonLabel;
btnLabel.text = buttonLabel;
}
}
}
The component definition has one parameter:
Var: buttonLabel, default value:Go, type:list
I'm trying to instance a movie clip that contains instances of this
variable. I get various compiler errors when that parent clip is on the
stage.
Argument Error 1063 (Argument Count Mismatch) expected 1, got 0, when
instancing a movieclip that contains these components. But in parent
movie clip, I am setting the params on the stage.
Thanks,
- Michael M.

Re: [Flashcoders] Error Instantiating Object
Hmmm... what's the rest of the Slide constructor? It sounds like maybe
that's where the error is...
Also, if you try running your Flash file in debug mode (Hit
Ctrl-Shift-Enter), the debugger will take control at the moment when you're
trying to access a null object, which usually helps you figure out what's
causing these kinds of problems.

I am an idiot! The debug mode did just what I needed! I was trying to add an event listener on a loader the line before doing the loader = new Loader(). Once solved that, now it is running (not correctly but that is another issue!). Thanks for responding so quickly and being so helpful. You never know when you get to a newsgroup whether people are good like the python newsgroup or awful like the comp.lang.javascript newsgroup. Thanks very much. I am sure you will hear more from me!

RE: [Flashcoders] inserting an MC in a TextField (and speaking to it)
Matt, I s'pose I focused too much on the second part of your question in my previous message. So anyway, if this src='com.myclasses.DropCap' actually works then more power to ya! If not: ActionScript 3.0 Language and Components Reference: src: Specifies the URL to an image or SWF file, or the linkage identifier for a movie clip symbol in the library. So, if you have a movieclip in your library with a linkage identifier of 'DropCap' (associated with a class 'com.myclasses.DropCap') you would use: var tString:String = img src='DropCap' id=DC0 style='padding:0px;margin:0px'/Lorem ipsom yadda yadda...; myTextField.htmlText = tString; myTextField.DC0.txt.text = Z; Regards, -Keith http://keithreinfeld.home.comcast.net ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
