Returns the inverse of the bits set in the argument.


prefix static func ~ (x: Int16) -> Int16


The bitwise NOT operator (~) is a prefix operator that returns a value in which all the bits of its argument are flipped: Bits that are 1 in the argument are 0 in the result, and bits that are 0 in the argument are 1 in the result. This is equivalent to the inverse of a set. For example:

let x: UInt8 = 5        // 0b00000101
let notX = ~x           // 0b11111010

Performing a bitwise NOT operation on 0 returns a value with every bit set to 1.

let allOnes = ~UInt8.min   // 0b11111111

Complexity: O(1).
