名詞

(computing) The number obtained by subtracting a given n-digit binary number from 2ⁿ-1 (which yields the same result as the logical complement).

日本語の意味

（コンピュータ）与えられた n 桁の2進数から 2ⁿ-1 を引くことで得られる数。これは各ビットを反転（0を1、1を0に）した結果と同じで、1の補数と呼ばれる。

意味（1）

(computing) The number obtained by subtracting a given n-digit binary number from 2ⁿ-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.

意味（2）

(computing) The convention by which bit patterns with high bit 0 represent positive numbers from 0 to 2ⁿ⁻¹-1 directly, while bit patterns with high bit 1 represent negative numbers from 0 to -(2ⁿ⁻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.
