But ieee754/flt-32/s_nearbyintf.c doesn't check the current rounding direction at all. -- http://sourceware.org/bugzilla/show_bug.cgi?id=2547 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ^ permalink raw reply [flat|nested] 4+ messages in thread
