Substantiivi

  1. (computing) The number obtained by subtracting a given n-digit binary number from 2n−1{\displaystyle 2^{n}-1} (which yields the same result as the logical complement).
  2. (computing) The convention by which bit patterns with high bit 0 represent positive numbers from 0 to 2n−1−1{\displaystyle 2^{n-1}-1} directly, while bit patterns with high bit 1 represent negative numbers from 0 to −(2n−1−1){\displaystyle -(2^{n-1}-1)}, n being the word size of the machine, and the numeric complement of a number is its ones' complement.

Esimerkit

  • The ones' complement of 0xAAAA is 0x5555 on a 16-bit machine, and 0xFFFF5555 on a 32-bit machine.
  • Computers that use ones' complement arithmetic have two representations for zero, all 0's and all 1's.
