  7. 	<div style="margin-left:  0px;">
    8. 

  8. 		The <b>BOOST_PP_NOT</b> macro performs a logical <i>NOT</i> on its operand.
    9. 

  9. 	</div>

  10. 	<h4>Usage</h4>
    11. 

  11. 		<div class="code">
    12. 

  12. 			<b>BOOST_PP_NOT</b>(<i>x</i>)
    13. 

  13. 		</div>
    14. 

  14. 	<h4>Arguments</h4>
    15. 

  15. 		<dl>
    16. 

  16. 			<dt>x</dt>
    17. 

  17. 			<dd>
    18. 

  18. 				The value to be converted.&nbsp;
    19. 

  19. 				Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_MAG</b>.
    20. 

  20. 			</dd>
    21. 

  21. 		</dl>
    22. 

  22. 	<h4>Remarks</h4>
    23. 

  23. 		<div>
    24. 

  24. 			If <i>x</i> is zero, this macro expands to <i>1</i>.&nbsp;
    25. 

  25. 			Otherwise, it expands to <i>0</i>.
    26. 

  26. 		</div>
    27. 

  27. 		<div>
    28. 

  28. 			This macro performs a boolean conversion on its operand before performing the logical <i>NOT</i> operation.&nbsp;
    29. 

  29. 			If that conversion is not necessary, use <b>BOOST_PP_COMPL</b> instead.
    30.
