* object.c (rb_obj_methods): list singleton methods if recur
argument is false; list all methods otherwise. * numeric.c (num_step): double epsilon to make "1.1.step(1.5,0.1)" to work. * ext/gdbm/gdbm.c (fgdbm_values_at): new method to replace select(index..). * ext/sdbm/init.c (fsdbm_values_at): ditto. * ext/dbm/dbm.c (fdbm_values_at): ditto. * ext/dbm/dbm.c (DBM::VERSION): defined. * ext/gdbm/testgdbm.rb: replace select with values_at. * ext/sdbm/testsdbm.rb: ditto. * ext/dbm/testdbm.rb: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@3758 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
