wont this work
i = ((i<<4)&255) | ((i>>4)&255); assuming that the data type of the number to hold is 8 bits and positive integers.

Then answer is
i = ( ((i<<8)&0xFFFF) | ((i >>8)&0xFFFF))

i = ( ((i<<8)&0xFFFF) | ((i >>8)&0xFFFF))(i>>8) would screw bigtime if i is a negative number. While right shifting, the vacated bits are not filled with zero but with the sign bit.
