如何将单元格中的数字四舍五入到 Excel 中的特定数字

Question

I have some product prices like

30,56
25,34
26,88
30,13

I want to to round them with a 0,50 limit

if the number is over x.50 to make it x.90 and if not make it x.50

is it possible with a function of VBA?

Answer 1

替代解决方案：

=INT(A1)+0.5+0.4*(MOD(A1,1)>0.5)

Answer 2

Use this formula to round:

=IF(A:A-INT(A:A)>0.5,INT(A:A)+0.9,INT(A:A)+0.5)

Explanation

It subtracts the integer part of the floating number so and tests if this is >0.5 so A:A-INT(A:A)>0.5 means (30.56 - 30) > 0.5 which is 0.56 > 0.5

The formula means something like that:

If (30.56 - 30) > 0.5 Then (30 + 0.9) Else (30 + 0.5)

Answer 3

Use IF, MOD and RoundDown

=IF(MOD(A2,1)>0.5,ROUNDDOWN(A2,0)+0.9,ROUNDDOWN(A2,0)+0.5)

You may want additional conditions to handle fringe cases like a price of 0.
