Bug #4022: Mistake in this cocient of logs followed by %1
http://redmine.ruby-lang.org/issues/show/4022

Author: Daniel Silberschmidt
Status: Open, Priority: Normal
Target version: 1.9.1
ruby -v: 1.9.1

I get a wrong answer when I apply the following expression: Math.log(4913)/Math.log(17) % 1
This happens in ruby 1.9.1 and in ruby 1.8.7
With other set of numbers the answers are correct

irb(main):001:0> Math.log(4913)/Math.log(17) % 1
=> 1.0
irb(main):002:0> Math.log(4913)/Math.log(17) 
=> 3.0
irb(main):003:0> 3.0 % 1
=> 0.0
irb(main):004:0> (Math.log(4913)/Math.log(17)) % 1
=> 1.0
