<div style="margin-left: 0px;">
The <b>BOOST_PP_BITAND</b> macro expands to the bitwise <i>AND</i> of its operands.
</div>
<h4>Usage</h4>
<div class="code">
<b>BOOST_PP_BITAND</b>(<i>x</i>, <i>y</i>)
</div>
<h4>Arguments</h4>
<dl>
<dt>x</dt>
<dd>
The left operand of the operation.&nbsp;
This value must expand to <i>0</i> or <i>1</i>.
</dd>
<dt>y</dt>
<dd>
The right operand of the operation.&nbsp;
This value must expand to <i>0</i> or <i>1</i>.
</dd>
</dl>
<h4>Remarks</h4>
<div>
If both <i>x</i> and <i>y</i> are <i>1</i>, this macro expands to <i>1</i>.&nbsp;
Otherwise, it expands to <i>0</i>.
</div>
<div>
This macro <i>does not</i> perform a boolean conversion on either operand before performing the bitwise <i>AND</i> operation.&nbsp;
If that conversion is necessary, use <b>BOOST_PP_AND</b> instead.
