The worst case is only about a 100 times slower now instead of 1000 times. I've not looked yet, but I think there is a case for capping maximum precision for worst case computation for sin (and all trigonometric functions) as well, so this could get even better. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
