Complement Tools
Master computer arithmetic complements for signed integer representation. Invert bits, compute Two’s Complement addition/subtraction, inspect sign bits, and determine register limits.
1's Complement Calculator
Calculate the 1’s complement of binary numbers by inverting every bit (bitwise NOT).
2's Complement Calculator
Compute the 2’s complement for signed binary numbers across 8, 16, 32, and 64-bit architectures.
9's Complement Calculator
Calculate the 9’s complement of decimal numbers by subtracting each digit from 9.
10's Complement Calculator
Calculate the 10’s complement of decimal numbers by taking the 9’s complement and adding 1.
1's ↔ 2's Complement Converter
Convert seamlessly between 1’s complement and 2’s complement representations with step-by-step proofs.
Signed Binary Calculator
Analyze signed binary numbers across Signed Magnitude, 1’s Complement, and 2’s Complement formats.
Sign-Magnitude Converter
Convert signed decimal numbers to Sign-Magnitude binary format and decode sign-magnitude bits.
1's Complement Representation
Inspect how positive and negative numbers map to bit patterns under 1’s Complement notation.
2's Complement Representation
Visualize 2’s complement bit mappings, negative weighting of the MSB, and asymmetric range limits.
Signed Integer Range Calculator
Calculate exact minimum and maximum limits for signed integers across custom and standard bit widths.
