我们讲述了IF的基本用法和IF的多重嵌套,如果第一次使用,或者不熟练会觉得IF的多重嵌套比较麻烦,或者不够清晰,IF的多重嵌套可以用IFS实现。
上节的IF嵌套案例:
比如一个班级的数学成绩,满分为100分,我们给学生的成绩进行评级,评级分3个
1.大于等于90的为优秀
2.大于等于80,小于90的为良好
3.大于等于60,小于80的为及格
3.小于60,为不及格
姓名 | 数学分数 | 评价(函数返回值) | 函数(通过字符比较) |
赵丽颖 | 90 | 优秀 | =IF(B90>=90,"优秀",IF(B90>=80,"良好",IF(B90>=60,"及格","不及格"))) |
杨幂 | 80 | 良好 | =IF(B91>=90,"优秀",IF(B91>=80,"良好",IF(B91>=60,"及格","不及格"))) |
迪丽热巴 | 67 | 及格 | =IF(B92>=90,"优秀",IF(B92>=80,"良好",IF(B92>=60,"及格","不及格"))) |
古力娜扎 | 89 | 良好 | =IF(B93>=90,"优秀",IF(B93>=80,"良好",IF(B93>=60,"及格","不及格"))) |
欧阳娜娜 | 86 | 良好 | =IF(B94>=90,"优秀",IF(B94>=80,"良好",IF(B94>=60,"及格","不及格"))) |
热依扎 | 55 | 不及格 | =IF(B95>=90,"优秀",IF(B95>=80,"良好",IF(B95>=60,"及格","不及格"))) |
姓名 | 数学分数 | 评价(函数返回值) | 函数(通过字符比较) |
赵丽颖 | 90 | 优秀 | =IFS(B98>=90,"优秀",B98>=80,"良好",B98>=60,"及格",B98<60,"不及格") |
杨幂 | 80 | 良好 | =IFS(B99>=90,"优秀",B99>=80,"良好",B99>=60,"及格",B99<60,"不及格") |
迪丽热巴 | 67 | 及格 | =IFS(B100>=90,"优秀",B100>=80,"良好",B100>=60,"及格",B100<60,"不及格") |
古力娜扎 | 89 | 良好 | =IFS(B101>=90,"优秀",B101>=80,"良好",B101>=60,"及格",B101<60,"不及格") |
欧阳娜娜 | 86 | 良好 | =IFS(B102>=90,"优秀",B102>=80,"良好",B102>=60,"及格",B102<60,"不及格") |
热依扎 | 55 | 不及格 | =IFS(B103>=90,"优秀",B103>=80,"良好",B103>=60,"及格",B103<60,"不及格") |
IFS(logical_test1,value_if_true,logical_test1,value_if_true,....)
IFS(表达式1,满足1的返回值,表达式2,满足2的返回值,表达式3,满足3的返回值,....)
