title: Is double 0.0 is greater or less than 0 in java
body: <p>I would like to ask for more clarification. Here my sample program</p>
  
  <pre><code>double diff = 7.500 - 7.500;
  System.out.println(diff); // result 0.0
  if (diff &gt; 0) {
      System.out.println("+" + diff ); //result +0.0
  } else {
      System.out.println("-" + diff ); //result -0.0
  }
  </code></pre>
  
  <p>My result is <strong>-0.0</strong>. My expectation is 0 == 0.0 then skip if else condition. But it enter to the else condition.Is double 0.0 is greater or less than 0?</p>
