     4   <category_description> &lt;p&gt;These panics represent errors raised by member functions of the &lt;code class="ApiItem"&gt;TRealX&lt;/code&gt; class. Typically, they are the result of illegal maths operations, such as dividing by zero, or operations which result in overflow.&lt;/p&gt;&lt;p&gt;The thread causing the panic is terminated.&lt;/p&gt;</category_description>
