Bug #4023: to_i pathological case in 1.8.7, 1.9.2
http://redmine.ruby-lang.org/issues/show/4023

Author: Chris Rosebrugh
Status: Open, Priority: Normal
Category: core
ruby -v: ruby 1.8.7 (2010-01-10 patchlevel 249) [i486-linux]

% /usr/bin/ruby -v
ruby 1.8.7 (2010-01-10 patchlevel 249) [i486-linux]
% /usr/bin/ruby -e "puts (4.55*100).to_i"
455
% /usr/bin/ruby -e "puts (4.56*100).to_i"
455
% /usr/bin/ruby -e "puts (4.57*100).to_i"
457


Also happens in 1.9.2 (2010-08-18) [i686-linux] (via http://tryruby.org/)

Should I really not expect (4.56*100).to_i to return 456?
