   8                 The <b>BOOST_PP_NOR</b> macro expands to the logical <i>NOR</i> of its operands.
   9         </div>
  10         <h4>Usage</h4>
  11                 <div class="code">
  12                         <b>BOOST_PP_NOR</b>(<i>p</i>, <i>q</i>)
  13                 </div>
  14         <h4>Arguments</h4>
  15                 <dl>
  16                         <dt>p</dt>
  17                         <dd>
  18                                 The left operand of the operation.&nbsp;
  19                                 Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_MAG</b>.
  20                         </dd>
  21                         <dt>q</dt>
  22                         <dd>
  23                                 The right operand of the operation.&nbsp;
  24                                 Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_MAG</b>.
  25                         </dd>
  26                 </dl>
  27         <h4>Remarks</h4>
  28                 <div>
  29                         If both <i>p</i> and <i>q</i> are both <i>0</i>, this macro expands to <i>1</i>.&nbsp;
  30                         Otherwise, it expands to <i>0</i>.
  31                 </div>
  32                 <div>
  33                         This macro performs a boolean conversion on each operand before performing the logical <i>NOR</i> operation.&nbsp;
  34                         If that conversion is not necessary, use <b>BOOST_PP_BITNOR</b> instead.
  35                 </div>
