   8                 The <b>BOOST_PP_COMPL</b> macro performs a bitwise inversion (bitwise <i>NOT</i> or one's complement) on its operand.
   9         </div>
  10         <h4>Usage</h4>
  11                 <div class="code">
  12                         <b>BOOST_PP_COMPL</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                                 This value must expand to <i>0</i> or <i>1</i>.
  20                         </dd>
  21                 </dl>
  22         <h4>Remarks</h4>
  23                 <div>
  24                         If <i>x</i> is <i>0</i>, this macro expands to <i>1</i>.&nbsp;
  25                         If <i>x</i> is <i>1</i>, this it expands to <i>0</i>.
  26                 </div>
  27                 <div>
  28                         This macro <i>does not</i> perform a boolean conversion on its operand before performing the inversion <i>OR</i> operation.&nbsp;
  29                         If that conversion is necessary, use <b>BOOST_PP_NOT</b> instead.
  30                 </div>
