title: comparing double values in C++
body: <p>I have following code for double comparision. Why I am getting not equal when I execute?</p>
  
  <pre><code>#include &lt;iostream&gt;
  #include &lt;cmath&gt;
  #include &lt;limits&gt; 
  
  bool AreDoubleSame(double dFirstVal, double dSecondVal)
  {
      return std::fabs(dFirstVal - dSecondVal) &lt; std::numeric_limits&lt;double&gt;::epsilon();
  }
  
  
  int main()
  {
  double dFirstDouble = 11.304;
  double dSecondDouble = 11.3043;
  
  if(AreDoubleSame(dFirstDouble , dSecondDouble ) )
  {
  std::cout &lt;&lt; "equal" &lt;&lt; std::endl;
  }
  else
  {
  std::cout &lt;&lt; "not equal" &lt;&lt; std::endl;
  }
  }
