Subject: [ruby-core:32660] [Ruby-Feature#3894][Open] Bug in the method Float and/or puts

Feature #3894: Bug in the method Float and/or puts
http://redmine.ruby-lang.org/issues/show/3894

Author: Karfter ERE
Status: Open, Priority: High

The bug is a problem in displaying a float, which can cause errors in calculating!!

example:

#ruby1.9.2 or ruby1.9.1 or ruby1.8.7
puts 2305843008139952128.0/23427.0
# != 98426730189096.005805267"
#Display 98426730189096.0 instead of 98426730189096.005805267
#This bug affects all versions, whatever the system x86 or x86_64 Linux

#Another error
puts 10.0/3.0
#ruby1.9.1 or ruby1.8.7
#good infinity
#3.33333333333333
#ruby1.9.2
#bad infinity
#3.3333333333333335

#ruby1.9.1 or ruby1.8.7
#good
puts 23427.0/17.0
#1378.05882352941
#ruby1.9.2
#No check, looks good!?
#1378.0588235294117
