Hi,

I got the site and understood fairly how to represent a negative number in binary form and left and right shift of postive numbers.

For example -13 binary is 1111 0011 and -13 >> 3 = 1111 1110.

I don't know how to interprete this as decimal number. Can anybody explain please?

Thanks in advance,

Madhuri.

Hi Jane,

The site given by you is so good but I still have the doubt for -13>>3 1111 1110 which is equal to -2. Even in your sight there is anumber -16>>2 which is equal to -4. The only part I did not understood is the calc part to arrive at -2 from

1111 1110 or in the -16 example. Please try to explain.
