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.
|
|
This value must expand to <i>0</i> or <i>1</i>.
|
|
</dd>
|
|
<dt>y</dt>
|
|
<dd>
|
|
The right operand of the operation.
|
|
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>.
|
|
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.
|
|
If that conversion is necessary, use <b>BOOST_PP_AND</b> instead.
