They are still bugs in the "it wou= ld be better to return the right result" sense, even if severity is much lower= ed and considerations of speed and man-power enter into the picture. For what it is worth, IEEE-754 since at least 2008 has recommended correctly-rounded exp10 and pown, both of which are simpler than the generic pow. --=20 You are receiving this mail because: You are on the CC list for the bug.=
