VBscript中的(数字和数字) [英] (Number and Number) in VBscript

问题描述

我在经典的ASP中有一些VB脚本，如下所示:

I have some VB script in classic ASP that looks like this:

if (x and y) > 0 then
    'do something
end if

它看起来像这样工作: (46和1)= 0 和 (47和1)= 1

It seems to work like this: (46 and 1) = 0 and (47 and 1) = 1

我不知道它是如何工作的.有人可以解释吗?

I don't understand how that works. Can someone explain that?

推荐答案

它是按位与.

    47 is 101111
AND  1 is 000001
        = 000001

同时

    46 is 101110
AND  1 is 000001
        = 000000
