Base 10 to Binary

The same 8 bits can mean different numbers depending on the representation. Enter a base 10 number to see its unsigned pattern and its two's complement pattern, with the steps.

try:

Unsigned (8-bit)

range 0 to 255. Every bit is a magnitude bit.

Two's complement (8-bit)

range -128 to 127. The leftmost bit has weight -128.

Positive and negative of the same integer

Same magnitude, two's complement. The negative is the positive pattern with every bit inverted, then 1 added.
