ones' complement

Noun

 * 1)  The number obtained by subtracting a given n-digit binary number from $$2^n - 1$$ (which yields the same result as the logical complement).
 * The ones' complement of 0xAAAA is 0x5555 on a 16-bit machine, and 0xFFFF5555 on a 32-bit machine.
 * 1)  The convention by which bit patterns with high bit 0 represent positive numbers from 0 to $$2^{n-1} - 1$$ directly, while bit patterns with high bit 1 represent negative numbers from 0 to $$-(2^{n-1} - 1)$$, n being the word size of the machine, and the numeric complement of a number is its ones' complement.
 * Computers that use ones' complement arithmetic have two representations for zero, all 0's and all 1's.
