| 8 | The <b>BOOST_PP_AND</b> macro expands to the logical <i>AND</i> of its operands. | |
| 9 | </div> | |
| 10 | <h4>Usage</h4> | |
| 11 | <div class="code"> | |
| 12 | <b>BOOST_PP_AND</b>(<i>p</i>, <i>q</i>) | |
| 13 | </div> | |
| 14 | <h4>Arguments</h4> | |
| 15 | <dl> | |
| 16 | <dt>p</dt> | |
| 17 | <dd> | |
| 18 | The left operand of the operation. | |
| 19 | Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_MAG</b>. | |
| 20 | </dd> | |
| 21 | <dt>q</dt> | |
| 22 | <dd> | |
| 23 | The right operand of the operation. | |
| 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 both <i>p</i> and <i>q</i> are non-zero, this macro expands to <i>1</i>. | |
| 30 | Otherwise, it expands to <i>0</i>. | |
| 31 | </div> | |
| 32 | <div> | |
| 33 | This macro performs a boolean conversion on each operand before performing the logical <i>AND</i> operation. | |
| 34 | If that conversion is not necessary, use <b>BOOST_PP_BITAND</b> instead. | |
| 35 | </div> | |
