Excel：将公式应用于另一个公式中列中的每个单元格

Question

I have a column of numbers. I want to ROUND the numbers in each cell of the column and then take the SUM of the cells.

Of course this can be done by creating another column with the rounded values and then taking its sum.

Say that I have 10 cells in column A. I round them to the nearest 0 using ROUND(A#,0) for A1 through A10. These new values go in B# . Then in B11 I have SUM(B1:B10) .

Is there a way to apply the ROUND forumla to each cell in column A within the SUM function so that I do not need to create another column of values?

Answer 1

SUMPRODUCT阵列中的“交易” 2

=SUMPRODUCT(ROUND(A1:A10,0))

Answer 2

Just use an array formula - enter with Ctrl + Shift + Enter .

=SUM(ROUND(A1:A10,0))

For example (also shows the rounded numbers in Column B to show it works, or you can see the magic with Formulas > Evaluate Formula .)
