Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_MAG</b>. </dd> <dt>q</dt> <dd> The right operand of the operation. Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_MAG</b>. </dd> </dl> <h4>Remarks</h4> <div> If either <i>p</i> or <i>q</i> is non-zero, this macro expands to <i>1</i>. Otherwise, it expands to <i>0</i>. </div> <div> This macro performs a boolean conversion on each operand before performing the logical <i>OR</i> operation. If that conversion is not necessary, use <b>BOOST_PP_BITOR</b> instead. </div> <h4>See Also</h4> <ul> <li><a href="bitor.html">BOOST_PP_BITOR</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/logical/or.hpp.html"><boost/preprocessor/logical/or.hpp></a> </div> <h4>Sample Code</h4> <div><pre> #include <<a href="../headers/logical/or.hpp.html">boost/preprocessor/logical/or.hpp</a>> <a href="or.html">BOOST_PP_OR</a>(4, 3) // expands to 1 <a href="or.html">BOOST_PP_OR</a>(5, 0) // expands to 1 </pre></div> </body> </html>
