从整数转换后，e +与字符串一起添加

Question

将整数转换为字符串后，在编译时将字符串与e +相加 就像在追踪中我得到的价值是90，在swf中它显示的是9.0e +

下面添加了百分比函数和teamxml函数。

public function getPlayerAttack(ourTeam:Boolean=true):String{
        var attackArr:Array=[];
        var num:int;
        var total:int=0;
        var _teamXML:XML;
        if (ourTeam)
            _teamXML=getOurTeamXml();
        else
            _teamXML=getOppTeamXml();

        for each (var playerList:XML in _teamXML.player.(@gp!="0")){

            if (playerList.@name!="TEAM"){
                var attackStat:String=getStat("attack_kills",playerList);
                num = int(attackStat);
                if(num >= 10)
                {
                total += num;
                attackArr.push(num);
                }
        }   
    }
var attackPer:int = getPercent(total,attackArr.length);
        var mytext:String = String(attackPer);
        trace(typeof mytext);
        return  mytext;
    }


public function getPercent(att:int,made:int):int{
        if (made==0)
            return 0;
        return Math.round((made/att)*100);
    }


    public function getOurTeamXml():XML{
        if (homeGame)
            return xml.team.(@vh=="H")[0];
        else
            return xml.team.(@vh=="V")[0];
    }

    public function getOppTeamXml():XML{
        if (homeGame)
            return xml.team.(@vh=="V")[0];
        else
            return xml.team.(@vh=="H")[0];
    }
