3.0自带函数2/8/10/16/32进制互换

function systemChange(txt:String,radix:uint,target:uint):String
{
  var num:Number = parseInt(txt,radix); //把2~32进制转换为10进制
  return num.toString(target); //把10进制转换为2~32进制
}

var txt = "FF6600"
txt = systemChange(txt,16,10); //16转10
trace(txt); //输出: 16737792
txt = systemChange(txt,10,8); //10转8
trace(txt); //输出: 77663000
txt = systemChange(txt,8,2); //8转2
trace(txt); //输出: 111111110110011000000000
txt = systemChange(txt,2,32); //2转32
trace(txt); //输出: fupg0
txt = systemChange(txt,32,16); //32转16
trace(txt); //输出: ff6600
