Is there a better way of writing v = (v == 0 ? 1 : 0); [closed]
...in different languages (VB). Yes a quick look-up will tell you that its an XOR operator and you will understand what its doing, but to many it may not be obvious at first glance. I don't think that means you need to quit your job.

How can I ensure that a division of integers is always rounded up?
...ositive by checking that the signs of both integers are identical. Integer xor operator '^' on the two values will result in a 0 sign-bit when this is the case, meaning a non-negative result, so the check (a ^ b) >= 0 determines that the result should have been positive before rounding. Also note...

Real world use cases of bitwise operators [closed]
...t into every area where these operators are used in graphics programming. XOR (or ^) is particularly interesting here because applying the same input a second time will undo the first. Older GUIs used to rely on this for selection highlighting and other overlays, in order to eliminate the need for...
What does numpy.random.seed(0) do?

How to get the Power of some Integer in Swift language?
...\(2 ^^ 3)") // Prints 2³ = 8
I used two carets so you can still use the XOR operator.
Update for Swift 3
In Swift 3 the "magic number" precedence is replaced by precedencegroups:
precedencegroup PowerPrecedence { higherThan: MultiplicationPrecedence }
