Below is a simple code that I made,


var array:Array =
[
	"44,5",
	"44,3",
	"44,2",
	"44,1",
	"44,4",
	"44,6",
	"5,99"
];
array.sort();
displayArray(array);

function displayArray(array:Array):void
{
	for(var i:int = 0; i < array.length; i++)
	{
		trace(array*);
	}
}

[COLOR=“Red”]It traces…[/COLOR]
44,1
44,2
44,3
44,4
44,5
44,6
5,99

[COLOR=“Green”]I expected it to be…[/COLOR]
5,99
44,1
44,2
44,3
44,4
44,5
44,6
