Subject: fractional extensions/hashing

when hashing, is it really necessary to hash the exact fractional depth, or is
it ok to just hash depth/PLY? I am thinking it is better to do the latter
because it saves space and also if the current depth is (say) 1.3 plies and the
hash table says 1.2, there wont be a cutoff, while the actual depth searched is
the same. or is it necessary because you might extend .7 plies on the next ply,
giving a premature cutoff?
