Re: LZ: manipulations

Which type of these manipulations is most efficient???


Is  ld a,5
     ld b,a
     ld a,50
     sub b


More efficient than


     ld a,5
     sub 50
     neg


And is a loop to add the number being multiplied to itself that # of times
(i.e.  6 * 8 = 8+8+8+8+8+8)
more efficient than a loop to shift left (6 * 8 = 6 shifted left three times)


Also, would the shifting method be able to work for #'s that aren't powers of
2 (odd #'s)


Finally, could someone explain division and how you would deal with
remainders.


Thanx,
