This is an online digital computation tool which is used to find the one’s & two’s compliment of a given binary, hex or decimal number.

1’s complement of a binary number is that where the number that can be obtained by changing all the ones to zeros and all zeros into ones of any given binary number.

However, 2’s complement is another binary number that can be obtained by adding 1 to one’s complement of a given binary number. It might sound a bit complicated though.

By using this calculator, it becomes so much easier to compute the decimal input. Just select the decimal radio button, simply type the decimal number in the text box that has been provided to you and click on the calculate button.

This will display the equivalent 1s or 2s complement of a given number. This calculator can support and in fact find out the 1’s & 2’s Complement for complex and intricate 8-bit, 16 bit and 32-bit binary numbers.
