I am new to bitwise thing in MSSQL.
Let's suppose there's a table of favorite foods
insert int fav_foods(food_name,bitwiseVal)
values('Pasta',1)
insert int fav_foods(food_name,bitwiseVal)
values('Chicken',2)

It's often explained that the reason for some of the imprecision
in C's definition is so that C can be implemented on different
kinds of machines -- say, those with 2's complement,
1's complement, or sign-magnitude arithmetic. But the followup
remark is sometimes also made that the choice of arithmetic isn't
completely unconstrained, since the bitwise operators seem to
presume a base-2 machine.

I know that the bitwise AND of 8 and 4 will return 0 or false and the
bitwise AND of 8 and 9 will return 1 or true but I don't know how to write
the synax for it in C#. I have a value that ranges from 0 to 15 and I need
to compare it to 15 in order to find if it contains the values 1, 2, 4, or
8.
To represent it more graphically, the value 1010 when ANDed with 1000 or
0010 will produce either true or a value greater than 0. I believe...

Hello,
I found some code that I could use in my application on the web, but it is
written in C#, and I would like to convert it to VB. And I am having
problems with one section. Is there anyone that could tell me how to
convert these two things?

I'm writing a map generator and I'm looking for a way to keep track of the
various terrain. I had a thought of using bitboards but I can't find a way
to bitwise AND two int's together and get a bool.
How do I get the proper response from:
IF (0x01 & 0x05)
My only recourse so far is to use the full if syntax:
IF ((0x01 & 0x05) > 0)

I'm learning to program in C and any tutorial or book that I read likes
to briefly touch on birdies operators and then move on without giving
any sort of example application of them. Call me what you will but I
cannot seem to see the purpose for bitwise operators. Especially the
operators bitwise OR ( | ) and bitwise AND ( & ), I'm just not getting
it. I have searched around and really haven't found anything that gave
explanation to why...

If one searches the forum for bitwise operators there are numerous
questions and very good answers to the perenial question about what
these operators do and why we need them.
So, having looked at all these, I approached K&R 2.9 headily!! ...but
not for long :-(
Quote:
The bitwise AND operator & is often used to mask off some set of bits;
for example,
n=n & 0177;

Can someone explain me bitwise expression?
few examples for every expression will be nice
x << y Left shift
x >y Right shift
x & y Bitwise AND
x | y Bitwise OR
x ^ y Bitwise XOR (exclusive OR)
~x Bitwise negation

I'm trying to generate a 4-byte unsigned integer in VB2005 that
encodes a number of bit-level variables. What I need to do is to be
able to compute a value for the uint that is based on specific values
for the constituent variables; the unit can then be passed to an
external DLL, which requires a function parameter in this form.
Unfortunately the only documentation I have for the external DLL is in
(I think) C++, which I'm struggling to...

I am creating a scheduling application which will allow users to
schedule recurring tasks, e.g., the user can set a task to run (M,T,W)
or (M,T,W,TH,F,S) etc. I want binary encode each day of the week and
use a bitwise OR and AND to determine which days the user selected
(and all the permutations):
const None = 0x0;
const Sunday = 0x1;
const Monday = 0x2;
const Tuesday = 0x4;

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
