Subject: RE: [flexcoders] Number Format issue. I need help.
Abdul,
thanks for your example it was very helpfull.... I added an extra text box and wanted to do some sum between the 2 boxes... very basic stuff...
function setOutput(){
var value1 : Number = parseFloat(in_ti.text);
var value2 : Number = parseFloat( in_ti2.text ) ;
var total : Number;
total = value1 + value2;
out_ti.text = getDecimalString(total);
// out_ti.text = numberformatter.format( getDecimalString(total) );
}
Well when I add 0.9990000344032 with 12345678901234.00000000000001 the result is: 12345678901235 ( no decimals )
or
0.9990000344032
+ 11111111111.00000000000001 = 11111111111.999 ( only the first 3... ) I would like to see all the decimals...
Can you help me? Am I missing something? Below you can find the modified code.
Thanks,
Valy

Show it as string, I mean internally calculate as number then convert number

I wrote a quick & dirty routine, that might help you.....There might be a
better way to do, this is what I have done using string operations...
<code>
function getDecimalString(n:Number):String
{
var s:String = n.toString();
if(n.toString().indexOf("e-")!=-1) {
var arr = n.toString().split("e-");
var v1 = Number(arr[0]);
var v2 = Number(arr[1]);
s = "0.";
var i = 0;
while(i++<v2) s+="0";
var s1 = v1.toString();
s+= s1.length>1 ? s1.split(".").join("") : s1;
}
return s;
}
</code>

Subject: Re: [flexcoders] Number Format issue. I need help.
I spent some time without figuring out a way to format a number in double
precision.
I have a grid and below it a total field that should sum the grid colums.
When I enter in the grid columns values as 0.00000008, 0.00000001 the result
field displays 9e-8, which is correct but I would like to display it as
0.00000009 instead.... Any suggestions?
Thanks,
Valy
