把23界周比赛状元有朋远来提到的”重心”公式改成通达信的

编写要求：

重心:=AMOUNT/(V*100); 两日重心:=(SUM(AMOUNT,2))/(SUM((V*100),2)); 三日重心:=(SUM(AMOUNT,3))/(SUM((V*100),3)); 四日重心:=(SUM(AMOUNT,4))/(SUM((V*100),4)); 上日重心:=ref(重心,1); 上两日重心:=ref(两日重心,1); 上三日重心:=ref(三日重心,1); 上四日重心:=ref(四日重心,1); 前日重心:=ref(重心,2); 前两日重心:=ref(两日重心,2); 前三日重心:=ref(三日重心,2); 前四日重心:=ref(四日重心,2); DRAWTEXTREL(0,100,'■今日重心:'+重心),COLORGREEN; DRAWTEXTREL(85,100,'■两日重心:'+两日重心),COLOR0099ef; DRAWTEXTREL(0,150,'■三日重心:'+三日重心),COLORGREEN; DRAWTEXTREL(85,150,'■四日重心:'+四日重心),COLOR0099ef; DRAWTEXTREL(185,100,'■上日重心:'+上日重心),COLORGREEN; DRAWTEXTREL(270,100,'■上两日重心:'+上两日重心),COLOR0099ef; DRAWTEXTREL(185,150,'■上三日重心:'+上三日重心),COLORGREEN; DRAWTEXTREL(270,150,'■上四日重心:'+上四日重心),COLOR0099ef; DRAWTEXTREL(370,100,'■前日重心:'+前日重心),COLORGREEN; DRAWTEXTREL(455,100,'■前两日重心:'+前两日重心),COLOR0099ef; DRAWTEXTREL(370,150,'■前三日重心:'+前三日重心),COLORGREEN; DRAWTEXTREL(455,150,'■前四日重心:'+前四日重心),COLOR0099ef;

解答：

?重心:=AMOUNT/(V*100);

两日重心:=(SUM(AMOUNT,2))/(SUM((V*100),2));
