| 8 | The <b>BOOST_PP_MAX_D</b> macro expands to the greater of its second and third arguments. | |
| 9 | It reenters <b>BOOST_PP_WHILE</b> with maximum efficiency. | |
| 10 | </div> | |
| 11 | <h4>Usage</h4> | |
| 12 | <div class="code"> | |
| 13 | <b>BOOST_PP_MAX_D</b>(<i>d</i>, <i>x</i>, <i>y</i>) | |
| 14 | </div> | |
| 15 | <h4>Arguments</h4> | |
| 16 | <dl> | |
| 17 | <dt>d</dt> | |
| 18 | <dd> | |
| 19 | The next available <b>BOOST_PP_WHILE</b> iteration. | |
| 20 | </dd> | |
| 21 | <dt>x</dt> | |
| 22 | <dd> | |
| 23 | The first operand. | |
| 24 | Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_MAG</b>. | |
| 25 | </dd> | |
| 26 | <dt>y</dt> | |
| 27 | <dd> | |
| 28 | The second operand. | |
| 29 | Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_MAG</b>. | |
| 30 | </dd> | |
| 31 | </dl> | |
| 32 | <h4>Remarks</h4> | |
| 33 | <div> | |
| 34 | This macro returns the greater of its first and second arguments or the value of both arguments if they are equal. | |
