=ROUND(SUM(K6:K8)/C16,2)这个怎么操作 =ROUND(SUM(C14:E14),2) =ROUND(SUM(D1:D3)/A4,2)怎样才能在这个单元格里同时显示kg/m3 k1+k2+k3+k4+k5+k6+k7+k8=20 3k1+3.5k2+4k3+4.5k4+5k5+5.5k6+6k7 =ROUND(IF(SUM(G14*0.0075*$M$2)>(G14-K14),G14-K14,SUM(G14*0.0 EXCLE表里{=SUM(ROUND(AJ5:AJ239, =SUM(INDIRECT("K8:K"&ROW()-1))这条公式是什么意思 round函数怎么用ROUND(ROUND(A1*A2+G2,2)2这个公式怎么解释啊 =IF(ISNA(VLOOKUP(K8,'1月'!D:E,2,0)),"",VLOOKUP(K8,'1月'!D:E,2, 求解Excel公式!=ROUND(SUM(LARGE(IF($A$2:$G$2="",0,$A$2:$G$2),COLU C16 x²+3x+2 =C16 5x+5 =IF(ISERROR(JSZ),"",ROUND(JSZ,2))公式是什么意思这个公式怎么用拜求解释还图解
