Two's Complement calculator

With this program, you can check a binary number in two's complement. The first bit is the sign bit such that a 1 means a negative number and a 0 means a positive.

I created this program because there are just so many out there that are rubbish and don't even work.

This calculator is powered by both PHP and ZPE.

You can find my binary calculator here.
