将数字转换成其他进制类型

5.将数字转换成其他进制类型，例如转换成16进制：

   <?xml version="1.0" encoding="utf-8"?>
   <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"

                             creationComplete="init()">
         <mx:Script>
                <![CDATA[
                       import mx.controls.Alert;
                       private var num:int = 123;
                       private function init():void
                       {
                              Alert.show(num.toString(16));
                       }
               ]]>
         </mx:Script>
   </mx:Application>
