Issue #1336 has been updated by Roger Pack. I like the recent change. Now it acts like this: >> 0.9 => 0.9 >> 2.1 - 3.0 => -0.8999999999999999 >> (2.1-3.0) == -0.9 => false Is this satisfactory, or would anyone still prefer Float#to_s => rounded, Float#inspect => non rounded (i.e. 0.9.inspect => "0.8999999999")? Just wondering since I brought up this mess :) I kind of like the current way. It hides some complexity while still explaining to end users why equality fails. Thanks for the update. -=r ---------------------------------------- http://redmine.ruby-lang.org/issues/show/1336 ---------------------------------------- http://redmine.ruby-lang.org
