Hi!

I have a code from an unknow author which I try to understand, but I
can't! Can you help me guys?

The code is:

Function bitcheck(ival As Integer, ibit As Integer)
bitcheck = 0
If (ival And 2 ^ ibit) 0 Then bitcheck = 1
End Function

But when I change the If statement for this:
If ival 0 and 2 ^ ibit 0 then bitcheck = 1

the function does not give the same answer. Why??

Thanks!

The code is:

Function bitcheck(ival As Integer, ibit As Integer)
* *bitcheck = 0
* *If (ival And 2 ^ ibit) 0 Then bitcheck = 1
End Function

in this code AND is used as binary operator:

debug.print 3 AND 2 ' - 11 and 10 - 10 = 2
debug.print 2 AND 2 ' - 10 and 10 - 10 = 2
debug.print 1 AND 2 ' - 01 and 10 - 00 = 0
debug.print 3 AND 1 ' - 11 and 01 - 01 = 1


* *If ival 0 and 2 ^ ibit 0 then bitcheck = 1

in your code AND is used as logic operator:
debug.print true and true - true
debig.print false and true - false

Hey Thanks Scossa!

I would never found it by myself!
