& operator with numbers

I found out something interesting in Python. When I input: 99 & 100 Out is 96. What does '&' do with these numbers? Why is the answer '96'? It looks so wierd...

Thank you in advance!

Solution

  • It's a bitwise operator. The manipulated unit is the binary representation of the numbers

    examples

    3 10
5 11 &
------
3 10 =

    and

    2 01
3 10 &
------
0 00 =

    Do the same for 99 & 100, you'll get out 96 in binary
