>> and << shift bits, not bytes. Numbers are internally
represented in digital computers using two-state bits.
The bitshift operators shift these bits.
For example 7 is 111 in binary. Shifting it one place left results in 1110 (digits coming from off the edge are zero), or 14. 111b shifted right once is 11 (a bit is shifted off), or 3. 7*2=14, and 7/2 is 3.5, the .5 is lost because of the one being shifted off. Hope this helps.
