|
||
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.
