The <b>BOOST_PP_ADD</b> macro expands to the sum of its arguments.
</div>
<h4>Usage</h4>
<div class="code">
<b>BOOST_PP_ADD</b>(<i>x</i>, <i>y</i>)
</div>
<h4>Arguments</h4>
<dl>
<dt>x</dt>
<dd>
The first addend of the operation.
Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_MAG</b>.
</dd>
<dt>y</dt>
<dd>
The second addend of the operation.
Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_MAG</b>.
</dd>
</dl>
<h4>Remarks</h4>
<div>
If the sum of <i>x</i> and <i>y</i> is greater than <b>BOOST_PP_LIMIT_MAG</b>, the result is saturated to <b>BOOST_PP_LIMIT_MAG</b>.
</div>
<div>
Previously, this macro could not be used inside <b>BOOST_PP_WHILE</b>.
There is no longer any such restriction.
It is more efficient, however, to use <b>BOOST_PP_ADD_D</b> in such a situation.
</div>
<div>
This macro is the most efficient when <i>x</i> is less than or equal to <i>y</i>.
However, the efficiency gain is not worth actually comparing the two arguments prior to invocation.
In other words, <i>x</i> should be the addend that is <i>most likely</i> to be the largest of the two operands.
