When to use Bitwise Operators during webdevelopment?

Question

Although I grasp the concept of Bitwise Operators, I can\'t say that I have come across many use cases during the webdevelopment process at which I had to resort to using Bi

Answer 1

My main use for bitwise operators could be relevant anywhere - representing a set of flags. For instance, you might have an integer in the database representing a set of security permissions for a user, and in your web app you would have to check those before continuing.

Those tend to only require & and | - e.g.

if ((permissions & Permission.CreateUser) != 0)
{
    ...
}

or

Permission requiredPermission = Permission.CreateUser
                                | Permission.ChangePassword;

Bit shifting operators are less useful in "business" applications in my experience.
