int foo = 0xF0; foo >>= 4; // foo == 0x0F foo <<= 2; // foo == 0x3C

EDIT: for those unaware of what bitshifting is...

0xF0 is %11110000 in binary:

1 2 3 4 5 6

hex bin 0xF0 %11110000 <-- original 0x78 %01111000 <-- right shift 1 0x3C 111100 <-- right shift 2 0x1E 011110 <-- right shift 3 0x3C 001111 <-- right shift 4

Right shifting by X is similar (but not exactly the same as) dividing by 2^X, and left shifting by X is similar (but not exactly the same as multiply by 2^X
