!!! Overview
[{$pagename}] (or complement) is a [Bitwise operation], is a unary operation that performs logical negation on each [bit], forming the ones' complement of the given [binary] value. [Bits] that are 0 become 1, and those that are 1 become 0.
For [example]:\\
[{$pagename}] 0111 ([decimal] 7) = 1000 ([decimal] 8)
[{$pagename}] is equal to the two's complement of the value minus one. If two's complement arithmetic is used, then [{$pagename}] x = -x − 1.
For [unsigned integer], [{$pagename}] of a number is the "mirror reflection" of the number across the half-way point of the unsigned integer's range. \\
For example, for 8-bit unsigned integers:\\
[{$pagename}] x = 255 - x\\
which can be visualized on a graph as a downward line that effectively "flips" an increasing range from 0 to 255, to a decreasing range from 255 to 0. A simple but illustrative example use is to invert a grayscale image where each pixel is stored as an unsigned integer.
