There's a WIP in https://svnweb.freebsd.org/base/user/peterj/ but I got caught up trying to work out how to perfectly multiply two doubles and am not currently working on it. I wonder if we should implement something like double cpow(double x, double y) { return cexp(y * clog(x)); } just to have something to resolve symbols. --=20 Peter Jeremy --r5Pyd7+fXNt84Ff3 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQJ8BAEBCgBmBQJYopeIXxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXRFRUIyOTg2QzMwNjcxRTc0RTY1QzIyN0Ux NkE1OTdBMEU0QTIwQjM0AAoJEBall6Dkogs0+CcP/3+VhuDq/VC92dCSnxCPEGj6 nYGKJeDF8kZ9U/Pc76g9hAO12/U60brmYQNd6AD32OH8XZOu4r4izfvlCEwBV1ge RkS5JvMkg9NjW4oU+vUmzAiUl2gMqwUU13XpesDblJryLjBy3JfvD/zl0XkR3s+D b7mioF+i3wKqlCBl0XC25EZ5M8yf7ES/1wwY23yv6sCee0XevhIw0ssc3PCLeqha GJgJOzwHR2uOZjLm0iirCN4sLOaRDRd55cgR2vIbatqm/khjqSQWAUbTt/GYFI0S 2JU2JpUoQwEjmeK/fxwVXn9FfRgI1L5/mwg3jJZDUfbibj+CF1BkOq0n6G+0BTaa CzLLcLAfA9+um/wtsFnIkijjbKMlfJ1AGprzJrm3xKrAKDmigKOdbn07HCsl4bdp tt5fL5gcF8DoO7s6xXrqxnNWFHCrTn2nPErCMxpr8QndbneR8ebUNhZK4MhP/Z1A VXqseAU9Wrwndr4NRwvA8VzPOKK+KF9yettEDoafcBPEQQyGJ88rLpLLNA96DtxX x1NioDv3n2rplWkxdbqS3wwV1b9fuWlu+OymglOfKGeDayBu2q/qOuh/BQwwvHjF IW34MBIqFZj8Y/ygsfowybOl+OYzuFZpXcWD2wqDlkhe2lwXga1lOzVuiwz2iVHY u/quk5pPDrr/LTH/rPnn =/62W -----END PGP SIGNATURE----- --r5Pyd7+fXNt84Ff3--
