Subject: [ruby-core:26045] [Bug #2189] Math.atanh(1) & Math.atanh(-1) should not raise an error

Issue #2189 has been updated by Marc-Andre Lafortune.


I should have mentioned that JRuby also returns ��Infinity for atanh(��1).

I would also recommend that whatever choice is made, Ruby 1.8.x should behave the same way as Ruby 1.9 (at least for x >= 8).
