title: Are there any differences between applying floor division and int() after dividing?
body: <p>It seems there are cases that the outputs are different between applying floor division and int() after dividing.
  Could you explain me the reasons or show me concrete cases?</p>
  
  <p><strong>Problem:</strong>
  int(a // b) is not equal to int(a / b)</p>
  
  <p><strong>Situation:</strong>
  a and b are integer and 0 &lt; a,b &lt;= 1e18</p>
  
  <p><strong>Setting:</strong>
  Python 3.4.3</p>
  
  <p><strong>Note:</strong>
  I cannot list up concrete cases because they are made by online judge test and test cases are not public.</p>
  
  <p>I hope your help.
  Thank you.</p>
