Converting From Decimal to Hex in Adobe Flex / ActionScript 3.0
June 16, 2009
In my most recent Adobe Flex project, I am storing color in the database as a hexadecimal number. However, Flex’s color picker widget (mx:ColorPicker) stores color values in decimal format. Now, I could use PHP’s dechex() function to convert the number, but I’d much rather send the data over in the proper format. After much struggling, I came across the following solution (it’s ridiculously easy):
var decimalNumber:int = 123456; var someVal:String = decimalNumber.toString(16);
Apparently, passing a value of “16″ to the toString function will convert a decimal number to hex. Go figure.

Note that this method will result in truncated hex values, e.g.,
var intVal:int = 26316;
var hexVal:String = intVal.toString(16);
hexVal = “66CC”;
I’m confused. How is the value of “66CC” a truncation of the integer value?
Thank YOU! LOL You are right. It’s so easy I never would’ve thought of that….
Thanks. This was really helpful!
Man this was a life saver. I actually looked for some days without finding an answer. I am doing an Intel 8085 simulator in flex and needed some values to be provided in hexadecimal. Once again thanks.
Thanks! This was useful. I fixed the truncation issue by doing this:
var hexString:String = backgroundColor_cp.selectedColor.toString( 16 );
while( hexString.length < 6 )
{
hexString = '0' + hexString;
}
_model.backgroundColorString = '#' + hexString;
Thank you very much!!
