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 }
infix operator ^^ : PowerPrecedence
func ^...

...move last 'e' to compensate for bencoding
return String.Join("", bytes.Select(b => b.ToString("X2")));
}
As I understand it, this hash does not include any information on how to locate the tracker, the client needs to find this out through other means (the announce url provided). This is j...
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.

The tilde operator in Python
...wos-complement representation of the integer are reversed (as in b <- b XOR 1 for each individual bit), and the result interpreted again as a twos-complement integer. So for integers, ~x is equivalent to (-x) - 1.
The reified form of the ~ operator is provided as operator.invert. To support th...

maximum value of int
...which is now set to maximum positive value.
We could also use a mask and xor but then we had to know the exact bitsize of the variable. With shifting in bits front, we don't have to know at any time how many bits the int has on machine or compiler nor need we include extra libraries.
