Everything about Ones' complement
Mathematics concept
The ones' complement of a binary number is the value obtained by inverting (flipping) all the bits in the number. The name "ones' complement" refers to the fact that such an inverted value, if added to the original, would always produce an "all ones" number. This mathematical operation is primarily of interest in computer science, where it has varying effects depending on how a specific computer represents numbers. Wikipedia →

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