   8                 The <b>BOOST_PP_BOOL</b> macro performs a boolean conversion on its operand.
   9         </div>
  10         <h4>Usage</h4>
  11                 <div class="code">
  12                         <b>BOOST_PP_BOOL</b>(<i>x</i>)
  13                 </div>
  14         <h4>Arguments</h4>
  15                 <dl>
  16                         <dt>x</dt>
  17                         <dd>
  18                                 The value to be converted.&nbsp;
  19                                 Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_MAG</b>.
  20                         </dd>
  21                 </dl>
  22         <h4>Remarks</h4>
  23                 <div>
  24                         If <i>x</i> is <i>0</i>, this macro expands to <i>0</i>.&nbsp;
  25                         Otherwise it expands to <i>1</i>.
  26                 </div>
