as per Ralf i also tested against and_bits...
results after many test runs (making sure cache was
flushed etc...) were that and_bits beat floor
by a reasonable margin (1.31 avg versus 1.48)
and (shockingly enough) sqrt -beat- and_bits
by a very significant margin (1.02avg vs 1.32 avg)
soooooooooooooooo
kudos to Rob for his predicition that it would
be near impossible to beat sqrt
and bad coder/bad coder to Rob for floor not
implementing and_bits in its algorithm :)
(jus kiddin) I'm sure you have a very good reason
for not being able to beat and_bits with your
floor routine Rob? hmmmmmm???? *poke* :)
*runs -very- fast to prevent being thwapped*
