+<p>Symbian platform floating-point arithmetic conforms to the IEEE754 specification.</p>
+<p>Most Symbian platform implementations do not have hardware floating-point
+support. As a result, floating-point arithmetic is noticeably less efficient
+than integer arithmetic. It should be avoided unless demanded by the problem
+type.</p>
