* lib/rational.rb: modified to support "quo".
* numeric.c (num_quo): should return most exact quotient value, i.e. float by default, rational if available. * numeric.c (num_div): "div" should return x.divmod(x)[0]. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@3399 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
