问题 单项选择题

如果已知一个Excel表格B1单元格是空白单元格,B2单元格的内容为数值2,B3单元格的内容为数值3,B4单元格的内容为数值4.5,B5单元格的内容为数值5.5,B6单元格的内容为“=COUNT(B1:B5)”,那么,B6单元格显示的内容应为______。

A.1
B.4
C.5
D.15

答案

参考答案:B

解析:在Excel中,COUNT函数返回包含数字以及包含参数列表中的数字的单元格的个数。函数COUNT在计数时,将把数字、日期或以文本代表的数据计算在内,但是错误值或其他无法转换成数字的文字将被忽略。COUNT(B1:B5)的统计范围是B1~B5这5个单元格,其中空白单元格被忽略,其他几个单元格被统计,共4个。
