This can be useful when you intend to align a vertical list of numbers so that the decimal points are in a straight line.

Note: unless you specify the forceLength parameter as a uint higher than 0, this function behaves just like the original function made by Flassari.

function numberFormat(number:*, maxDecimals:int = 2, forceDecimals:Boolean = false, siStyle:Boolean = true, forceLength:uint = 0, indentUnit:String = " "):String {
	var i:int = 0, inc:Number = Math.pow(10, maxDecimals), str:String = String(Math.round(inc * Number(number))/inc), indent:String = "";
	var hasSep:Boolean = str.indexOf(".") == -1, sep:int = hasSep ? str.length : str.indexOf(".");
	var ret:String = (hasSep && !forceDecimals ? "" : (siStyle ? "," : ".")) + str.substr(sep+1);
	if (forceDecimals) for (var j:int = 0; j <= maxDecimals - (str.length - (hasSep ? sep-1 : sep)); j++) ret += "0";
	while (i + 3 < (str.substr(0, 1) == "-" ? sep-1 : sep)) ret = (siStyle ? "." : ",") + str.substr(sep - (i += 3), 3) + ret;
	if(forceLength != 0) for(j = sep + i / 3; j < forceLength; j++) indent += indentUnit;
	return indent + str.substr(0, sep - i) + ret;
}
