   8                 The <b>BOOST_PP_LESS_EQUAL</b> macro compares two values for equality or lesser magnitude.
   9         </div>
  10         <h4>Usage</h4>
  11                 <div class="code">
  12                         <b>BOOST_PP_LESS_EQUAL</b>(<i>x</i>, <i>y</i>)
  13                 </div>
  14         <h4>Arguments</h4>
  15                 <dl>
  16                         <dt>x</dt>
  17                         <dd>
  18                                 The left operand of the comparison.&nbsp;
  19                                 Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_MAG</b>.
  20                         </dd>
  21                         <dt>y</dt>
  22                         <dd>
  23                                 The right operand of the comparison.&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 <i>x</i> is lesser than or equal to <i>y</i>, this macro expands to <i>1</i>.&nbsp;
  30                         Otherwise, it expands to <i>0</i>.
  31                 </div>
  32                 <div>
  33                         Previously, this macro could not be used inside <b>BOOST_PP_WHILE</b>.&nbsp;
  34                         There is no longer any such restriction.&nbsp;
  35                         It is more efficient, however, to use <b>BOOST_PP_LESS_EQUAL_D</b> in such a situation.
  36                 </div>
