diminished radix complement; radix-minus-one complement
A computing term for the complement obtained by subtracting each digit from the radix minus one. Used in binary (ones' complement) and decimal (nines' complement) systems.
In binary, the diminished radix complement is called ones' complement.
十進法の減基数の補数は9の補数である。
The diminished radix complement in decimal is the nines' complement.
基数の補数 (radix complement) is the complement obtained by subtracting each digit from the radix and adding one, e.g., two's complement in binary. 減基数の補数 is one less than the radix complement.
Compound of 減基数 (げんきすう, 'diminished radix') + の (possessive particle) + 補数 (ほすう, 'complement'). The term is a direct translation of the English 'diminished radix complement'.
