Binary workshop

About this app

Place values you can touch: flip bits and watch the decimal, hex and octal values emerge — including the remainder algorithm. In complement mode the MSB visibly weighs negative (−128 + 8 + 2 = −118); in addition mode the carries travel like in column addition — including overflow when the carry out of the MSB is lost.
