AS3.0中的运算符和AS2.0中的一样，运算符对应相应的表达式。

package { 
    import flash.display.Sprite; 
    public class EODemo extends Sprite

        public function EODemo(){ 
        //数值运算符 
        var price:Number=400+50; 
        trace(price); 
        price=price+50; 
        trace(price); 
        price=price*1.2;

        //字符串运算符 
        var bookTitle:String="AS 3.0 "; 
        bookTitle=bookTitle+"＆ Flex 2.0实战";

        //条件运算符 
        trace((price>100) ? "大于100" : "不大于100");

        //点 (.) 运算符 
        trace(fruits.length);   
        //按位运算符(|和>>) 
        fruits.sort(Array.CASEINSENSITIVE | Array.DESCENDING);
