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

Goodmorning, i am trying to make a formula that makes for example 30.60

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?
Best regards,
Jim

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 :)

I now have this :
total= String(Number(600) / 100 * Number(5.1));
cash = newArray;
cash = total.split(.);
if (cash.length == 1)
{
total+= .00;
}
else if (cash[cash.length - 1].length == 1)
{
total+= 0;
}
It's doing the job.

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 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,
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,
