四舍六入五成雙EXCEL實現(xiàn)

=IF(MID(A2,FIND(".",A2,1)+B2+1,1)*1<5,LEFT(A2,B2+FIND(".",A2,1)),IF(AND(MID(A2,FIND(".",A2,1)+B2+1,1)*1=5,RIGHT(A2,LEN(A2)-FIND(".",A2,1)-B2)*1=5*POWER(10,LEN(A2)-FIND(".",A2,1)-B2-1),INT(MID(A2,FIND(".",A2,1)+B2,1)*1/2)=MID(A2,FIND(".",A2,1)+B2,1)*1/2),LEFT(A2,B2+FIND(".",A2,1)),LEFT(A2,B2+FIND(".",A2,1))*1+POWER(10,-B2)))

解析：
A2存有待修約值，
B2存有修約小數(shù)點保留位數(shù)N，
邏輯：如果小數(shù)點后第N+1位數(shù)字小于5 則結(jié)果為不進位；
         如果小數(shù)點后第N+1位數(shù)字等于5 且第N數(shù)數(shù)字為偶數(shù)則結(jié)果為不進位
         否則結(jié)果全部進位。


返回進位結(jié)果LEFT(A2,B2+FIND(".",A2,1))*1+POWER(10,-B2)，
返回不進位結(jié)果LEFT(A2,B2+FIND(".",A2,1))
不進位條件：
     小數(shù)點N+1位數(shù)字MID(A2,FIND(".",A2,1)+B2+1,1)*1小于5；
     小數(shù)點N+1位數(shù)字MID(A2,FIND(".",A2,1)+B2+1,1)*1等于5，且后面全為0的
     條件RIGHT(A2,LEN(A2)-FIND(".",A2,1)-B2)*1=5*POWER(10,LEN(A2)-FIND(".",A2,1)-B2-1)；         

進位條件：不進位便是進位。

附：
奇偶判定：INT(MID(A2,FIND(".",A2,1)+B2,1)*1/2)=MID(A2,FIND(".",A2,1)+B2,1)*1/2)，成立為偶數(shù)
進位后：加數(shù)值POWER(10,-B2)
小數(shù)點從左到右所在位置：FIND(".",A2,1)

有效數(shù)字大于1，求公式可在附件中下載。已更新。如有好的意見和建議，請發(fā)貼。

EXCEL受限于浮點運算機制，是比較難處理 的。

確實碰到這種情況，改變了思路，才破解了。很不容易。不用宏程序解決確實太難了。我用宏程序測試過，目前還沒有發(fā)現(xiàn)異常，宏程序在文件里面。可運行

還有有效數(shù)字，里面公式太復(fù)雜了，就不作解析了。

謝謝你的分享！

k7，原創(chuàng)作品，多多提意見，后期好改進

公式還有一個能改進的點，小數(shù)點后面最后一位為0時，小數(shù)位保留就會出現(xiàn)異常

先進的科學(xué)技術(shù)，提高生產(chǎn)力水平，不錯

如果數(shù)據(jù)大于0.1可以用下面的公式。小于0.1就不大適用了。

假如原始數(shù)據(jù)在A1，則在B1或C1或D1其他列中輸入以下
=IF(TRUNC(MOD(ABS(A1*POWER(10,2)),2),2)=0.5,ROUNDDOWN(A1,2),ROUND(A1,2))

如果數(shù)據(jù)不在A1處，如在B1處，則需要把公式里的A1改成B1即可，照此類推
上面公式給出的是保留2位小數(shù)，如果保留3位，就把2改成3，保留0位則改成0，保留十位-1，百位-2，照此類推
=IF(TRUNC(MOD(ABS(A1*POWER(10,2)),2),2)=0.5,ROUNDDOWN(A1,2),ROUND(A1,2))
