title: double and accuracy
body: <p>Using <code>long double</code> I get <code>18/19 = 0.947368421052631578...</code>, and <code>947368421052631578</code> is the repeating decimal. Using <code>double</code> I get <code>0.947368421052631526...</code> However, the former is correct. Why such an incorrect result?</p>
  
  <p>Thanks for help.</p>
