<html> <head> <title>BOOST_PP_LESS</title> <link rel="stylesheet" type="text/css" href="../styles.css"> </head> <body> <div style="margin-left: 0px;"> The <b>BOOST_PP_LESS</b> macro compares two values for lesser magnitude. </div> <h4>Usage</h4> <div class="code"> <b>BOOST_PP_LESS</b>(<i>x</i>, <i>y</i>) </div> <h4>Arguments</h4> <dl> <dt>x</dt> <dd> The left operand of the comparison. Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_MAG</b>. </dd> <dt>y</dt> <dd> The right operand of the comparison. Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_MAG</b>. </dd> </dl> <h4>Remarks</h4> <div> If <i>x</i> is less than <i>y</i>, this macro expands to <i>1</i>. Otherwise, it expands to <i>0</i>. </div> <div> Previously, this macro could not be used inside <b>BOOST_PP_WHILE</b>. There is no longer any such restriction. It is more efficient, however, to use <b>BOOST_PP_LESS_D</b> in such a situation. </div> <h4>See Also</h4> <ul> <li><a href="less_d.html">BOOST_PP_LESS_D</a></li> <li><a href="limit_mag.html">BOOST_PP_LIMIT_MAG</a></li> </ul> <h4>Requirements</h4> <div> <b>Header:</b> <a href="../headers/comparison/less.hpp.html"><boost/preprocessor/comparison/less.hpp></a> </div> <h4>Sample Code</h4> <div><pre> #include <<a href="../headers/comparison/less.hpp.html">boost/preprocessor/comparison/less.hpp</a>> <a href="less.html">BOOST_PP_LESS</a>(4, 3) // expands to 0 <a href="less.html">BOOST_PP_LESS</a>(3, 4) // expands to 1 </pre></div> </body> </html>
