<div style="margin-left: 0px;">
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.
