| The <b>BOOST_PP_MOD_D</b> macro expands to the modulus of its second and third arguments. |
| It reenters <b>BOOST_PP_WHILE</b> with maximum efficiency. |
| </div> |
| <h4>Usage</h4> |
| <div class="code"> |
| <b>BOOST_PP_MOD_D</b>(<i>d</i>, <i>x</i>, <i>y</i>) |
| </div> |
| <h4>Arguments</h4> |
| <dl> |
| <dt>d</dt> |
| <dd> |
| The next available <b>BOOST_PP_WHILE</b> iteration. |
| </dd> |
| <dt>x</dt> |
| <dd> |
| The dividend (numerator) of the operation. |
| Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_MAG</b>. |
| </dd> |
| <dt>y</dt> |
| <dd> |
| The divisor (denominator) of the operation. |
| Valid values range from <i>1</i> to <b>BOOST_PP_LIMIT_MAG</b>. |
| </dd> |
| </dl> |
| <h4>Remarks</h4> |
| <div> |
| If <i>y</i> is <i>0</i>, the result is undefined. |
