From adde0a94a2828df8a28207a0d4c90ae97c7df9f2 Mon Sep 17 00:00:00 2001 From: odaira Date: Fri, 4 Mar 2016 22:43:31 +0000 Subject: [PATCH] * test/-ext-/float/test_nextafter.rb: In AIX, nextafter(+0.0,-0.0)=+0.0, and nextafter(-0.0,+0.0)=-0.0, but they should return -0.0 and +0.0, respectively. This is a known bug in nextafter(3) on AIX, so skip related tests. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@54003 b2dd03c8-39d4-4d8f-98ff-823fe69b080e --- ChangeLog | 7 +++++++ test/-ext-/float/test_nextafter.rb | 13 ++++++++++--- 2 files changed, 17 insertions(+), 3 deletions(-) diff --git a/ChangeLog b/ChangeLog index 6729e9a397..9924ae7c6f 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,10 @@ +Sat Mar 5 07:36:27 2016 Rei Odaira + + * test/-ext-/float/test_nextafter.rb: In AIX, + nextafter(+0.0,-0.0)=+0.0, and nextafter(-0.0,+0.0)=-0.0, + but they should return -0.0 and +0.0, respectively.
