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

max value of integer
...tter now, thanks! Too much Python, I suppose. I avoid ^ since it's usually xor

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...
__FILE__, __LINE__, and __FUNCTION__ usage in C++
... It's possible with constexpr that uses a lookup table or bitwise XOR, etc. to obfuscate any string literals in your binary. There are various examples out there if you search. Of course obfuscation is just obfuscation and not security, but if you don't want to make your files and functions...
How to get memory available or used in C#

One note. In C# ^ is bitwise XOR, not power. So just use proc.PrivateMemorySize64 / (1024*1024), or proc.PrivateMemorySize64 / (1 << 20)

subtle differences between JavaScript and Lua [closed]
...xample, if foo ~= 20 then ... end.
Lua 5.3 and up use ~ for binary bitwise XOR, whereas JS uses ^.
In Lua, any type of value (except nil and NaN) can be used to index a table. In JavaScript, all non-string types (except Symbol) are converted to strings before being used to index an object. For exam...

How can I apply a function to every row/column of a matrix in MATLAB?
...tors — <, <=, >, >=, ==, ~=
Logical operators — &, |, xor
Bit-wise functions — bitand, bitor, bitxor
Elementary math functions — max, min, mod, rem, hypot, atan2, atan2d
For example, you can calculate the mean of each column in a matrix A,
and then subtract the vec...
