Unsigned binary and conversions

Unsigned binary just means normal binary.

In 8 bit binary this is the numbers you can use. The highest 8 bit number you can get is 255 and anything over is an overflow

128 64 32 16 8 4 2 1

0     1    0   0   1 1 1 0   = 78

 

To convert binary to denary you write the denary equivalent to each binary number above and the ones with a 1 you add together.

To convert back to binary you go back to front and take each number away that the denary number goes into until it is all gone.
