Re: [Discuss-gnuradio] VOLK: fast way to log10()?

[Brian Padalino]

It sounded like a fun and interesting question, so apparently there is
a little post from 2007 about a new implementation in C licensed under
GPLv2:

  https://sourceware.org/ml/libc-alpha/2007-06/msg00124.html

It would be interesting to compare and see if the results are
beneficial even if no VOLK is involved.
