title: Java double epsilon
body: <p>I'm currently in the need of an <a href="http://en.wikipedia.org/wiki/Machine_epsilon" rel="noreferrer">epsilon</a> of type <code>double</code> (preferred are constants in java's libraries instead of own implementations/definitions)<p>
  As far as I can see <code>Double</code> has <code>MIN_VALUE</code> and <code>MAX_VALUE</code> as static members.<p>
  Why there is no <code>EPSILON</code>?<p>
  What would a <code>epsilon&lt;double&gt;</code> be?<p>
  Are there any differences to a <code>std::numeric_limits&lt; double &gt;::epsilon()</code>?</p>
  
  <p>Epsilon: The difference between 1 and the smallest value greater than 1 that is representable for the data type.</p>
