| 8 | The <b>BOOST_PP_MIN</b> macro expands to the lesser of its two arguments. | |
| 9 | </div> | |
| 10 | <h4>Usage</h4> | |
| 11 | <div class="code"> | |
| 12 | <b>BOOST_PP_MIN</b>(<i>x</i>, <i>y</i>) | |
| 13 | </div> | |
| 14 | <h4>Arguments</h4> | |
| 15 | <dl> | |
| 16 | <dt>x</dt> | |
| 17 | <dd> | |
| 18 | The first operand. | |
| 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 second operand. | |
| 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 | This macro returns the lesser of its two arguments or the value of both arguments if they are equal. | |
| 30 | </div> | |
| 31 | <div> | |
| 32 | Previously, this macro could not be used inside <b>BOOST_PP_WHILE</b>. | |
| 33 | There is no longer any such restriction. | |
| 34 | It is more efficient, however, to use <b>BOOST_PP_MIN_D</b> in such a situation. | |
| 35 | </div> | |
