As you know, those may be Integers, Longs or Doubles but also BigIntegers or BigDecimals. So what to do?</p> <ol> <li>Number does not implement <a href="http://docs.oracle.com/javase/7/docs/api/java/lang/Comparable.html" rel="nofollow noreferrer">Comparable</a>.</li> <li>Can't use <code>doubleValue()</code> as there might be a loss of precision from BigDecimals or BigIntegers.</li> </ol> <p>Do I really have to go into instance-testing and casting? There <em>must</em> be some library that does this. But I've already checked Apache Commons and Guava with no luck.</p> <p><strong>Edit 1:</strong> Comments pointed this out: <a href="https://stackoverflow.com/q/2683202/1374678">Comparing the values of two generic Numbers</a>. It has a solution that converts everything to a BigDecimal using <code>toString()</code>. Is there really no better way to do this?</p> <p><strong>Edit 2:</strong> I just posted <a href="https://stackoverflow.com/a/12884075/1374678">my own version as an answer to the other question</a>. It should be more efficient and robust than the accepted answer.</p>
