Issue #1560 has been updated by Roger Pack. I think it would be nice for this to be fixed before 1.9.2 is released. Any objections to reopening this or should I open a new ticket? $ time ~/installs/ruby_trunk_installed/bin/ruby -v floats.rb ruby 1.9.2dev (2010-03-15 trunk 26942) [i686-linux] Total number of insane floating point divisions in 10 seconds is 1_716_186 real 0m10.049s $ time ruby -v floats.rb ruby 1.9.1p243 (2009-07-16 revision 24175) [i686-linux] Total number of insane floating point divisions in 10 seconds is 5_798_735 real 0m10.175s This type of performance drop scares me.
