  <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>

      <panic_description>&lt;p&gt;This panic is raised by &lt;code&gt;operator/=&lt;/code&gt; of a &lt;code class="ApiItem"&gt;TRealX&lt;/code&gt;, when the divisor is zero&lt;/p&gt;</panic_description>
