asp classic - (Number and Number) in VBscript

Question

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

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

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

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

Answer 1

It's a Bitwise AND.

    47 is 101111
AND  1 is 000001
        = 000001

while

    46 is 101110
AND  1 is 000001
        = 000000
