嵌套的if AND语句-Google表格

Question

我尝试编写的嵌套if语句不断返回错误，但我看不到哪里。 我见过类似的线程，但没有一个具有可行的语法。 我尝试过使用和不使用and语句。 非常简单地查看单元格（C5）中的值，并基于C5中的数字返回相应的基于值的值。

=if(C5>84.5,1,if(and(C5<=84.5,C5>79.5,1.3,if(and(C5<=79.5,C5>74.5,1.7,if(and(C5<=74.5,C5>69.5,2,if(and(C5<=69.5,C5>64.5,2.3,if(and(C5<=64.5,C5>59.5,2.7,if(and(C5<=59.5,C5>54.5,3,if(and(C5<=54.5,C5>49.5,3.3,if(and(C5<=49.5,C5>44.5,3.7,if(and(C5<=44.5,C5>=40,4,if(C5<40,5))))))))))))))))))))

我期望输出范围为1到5，具体取决于单元格C5中的值，但我不断收到以下错误

IF参数个数错误。 预期2到3个参数，但有1个参数

Answer 1

您系统地忘记了关闭and()函数的括号。 尝试这个：

=if(C5>84.5,1,if(and(C5<=84.5,C5>79.5),1.3,if(and(C5<=79.5,C5>74.5),1.7,if(and(C5<=74.5,C5>69.5),2,if(and(C5<=69.5,C5>64.5),2.3,if(and(C5<=64.5,C5>59.5),2.7,if(and(C5<=59.5,C5>54.5),3,if(and(C5<=54.5,C5>49.5),3.3,if(and(C5<=49.5,C5>44.5),3.7,if(and(C5<=44.5,C5>=40),4,if(C5<40,5)))))))))))

如果需要ArrayFormula，请使用：

=ARRAYFORMULA(
 IF( C5:C >  84.5, 1,
 IF((C5:C <= 84.5) * (C5:C >  79.5), 1.3,
 IF((C5:C <= 79.5) * (C5:C >  74.5), 1.7,
 IF((C5:C <= 74.5) * (C5:C >  69.5), 2,
 IF((C5:C <= 69.5) * (C5:C >  64.5), 2.3,
 IF((C5:C <= 64.5) * (C5:C >  59.5), 2.7,
 IF((C5:C <= 59.5) * (C5:C >  54.5), 3,
 IF((C5:C <= 54.5) * (C5:C >  49.5), 3.3,
 IF((C5:C <= 49.5) * (C5:C >  44.5), 3.7,
 IF((C5:C <= 44.5) * (C5:C >= 40),   4,
 IF( C5:C <  40, 5))))))))))))
