Two’s (2's) complement Calculator

Two's complement calculator can help you calculate the binary value of negative decimals. This two’s complement converter will find two complements of the binary number and convert it to the corresponding negative decimal.

How to convert decimals into binary numbers?

Converting decimals into binary requires effort but it is easy to understand. Let’s consider we want to convert 15 into binary digits.

We’ll first write the powers of two to the closest maximum. In this case 2 to the power of 4.

Two's

So the binary representation of 15 is “1111” (Verified by AllMath).

On the other hand, 2's complement calculator can do all processes in less than a minute. Furthermore, you can also convert 2's complement to a decimal using our 2s complement to the decimal tool.

How to find two’s complement of a negative integer?

To find two’s complement of a negative integer, firstly convert its positive integer let’s say “x” to binary form. Then find its one’s complement and add 1 to it. The answer is the binary representation of the negative integer “-x”.

If the method to find two’s complement of a negative integer seems difficult, use the 2s complement calculator to avoid the hassle.
