As requested by Isaac. I now have my own account there so I can submit it.

Thanks.

You're welcome. It'll be interesting to see how it performs on Isaacs machine.

Unfortunately this performed worse than the old version on the benchmarksgame server. :(

Yeah, I forgot that Isaac uses this ancient pre-AVX Core 2, which cannot do 256 bit float arithmetic :frown:.

On the other hand, I have an idea on how to improve perf even without that. Stay tuned.
