this</code> is greater than <code>other</code>.</p>
<p>The ordering represented by this method is a total ordering of <a href="dart-core/num-class.html">num</a>
values. All distinct doubles are non-equal, as are all distinct integers,
but integers are equal to doubles if they have the same numerical
value.</p>
<p>For doubles, the <code>compareTo</code> operation is different from the partial
ordering given by <a href="dart-core/num/operator_equals.html">operator==</a>, <a href="dart-core/num/operator_less.h
