困惑！！ [英] CONFUSED!!

问题描述

看看下面的VB代码。第一个MsgBox显示数字2

而第二个是6.为什么？为什么2.5被四舍五入为2和5.5是

四舍五入为6 ??


Dim i As Integer = 5/2


MsgBox（i）


Dim j As Integer = 11/2

MsgBox（j）

Have a look at the follwoing VB-code. The first MsgBox shows the number 2
while the second one 6. WHY? How come 2.5 is rounded off to 2 and 5.5 is
rounded off to 6??

Dim i As Integer = 5 / 2

MsgBox(i)

Dim j As Integer = 11 / 2

MsgBox(j)

推荐答案

如果可能的话，更改为整数除法如果不是从整数类型更改并且

他们尝试舍入，我遇到了同样的问题..令我感到困惑直到我

只用int division解决它而放弃了。


Dim i As Integer = 5 \2


关于为什么圆角差异的答案..我不知道？

Change to integer division if possible if not change from integer type and
they try rounding, i ran in to the same problem .. it baffled me till i
solved it using int division only and gave up.

Dim i As Integer = 5 \2

as to your answer of why the rounding difference .. i dunno?

有一个看看下面的VB代码。第一个MsgBox显示数字2
而第二个显示数字6.为什么？为什么2.5将四舍五入为2而5.5则四舍五入为6 ??

Dim i As Integer = 5/2

MsgBox（i）

Dim j As Integer = 11/2

MsgBox（j）

Have a look at the follwoing VB-code. The first MsgBox shows the number 2
while the second one 6. WHY? How come 2.5 is rounded off to 2 and 5.5 is

Dim i As Integer = 5 / 2

MsgBox(i)

Dim j As Integer = 11 / 2

MsgBox(j)

我忘记了这种类型的舍入的名称，但奇数和偶数数字是不同的。尝试7/2和9/2，并按照处理方式查看

的相似之处。


我会看看我是否可以挖掘关于四舍五入和发布网址的文章。

I forget the name of this type of rounding, but odd and even numbers are
rounded differently. Try 7/2 and 9/2, as well and see the similarities in
the way it is handled.

I will see if I can dig up the article on rounding and post an URL.

数学四舍五入（右词？）意味着转到下一个_even_数字。

Mathematical rounding (right words?) means round to the next _even_ number.
