But the result glibc gives is still 0X1P-24, so confirmed (though I don't know how practical getting this very accurate is). -- 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. ^ permalink raw reply [flat|nested] 3+ messages in thread
