| 8 | The <b>BOOST_PP_BITAND</b> macro expands to the bitwise <i>AND</i> of its operands. |
|---|
| 9 | </div> |
|---|
| 10 | <h4>Usage</h4> |
|---|
| 11 | <div class="code"> |
|---|
| 12 | <b>BOOST_PP_BITAND</b>(<i>x</i>, <i>y</i>) |
|---|
| 13 | </div> |
|---|
| 14 | <h4>Arguments</h4> |
|---|
| 15 | <dl> |
|---|
| 16 | <dt>x</dt> |
|---|
| 17 | <dd> |
|---|
| 18 | The left operand of the operation. |
|---|
| 19 | This value must expand to <i>0</i> or <i>1</i>. |
|---|
| 20 | </dd> |
|---|
| 21 | <dt>y</dt> |
|---|
| 22 | <dd> |
|---|
| 23 | The right operand of the operation. |
|---|
| 24 | This value must expand to <i>0</i> or <i>1</i>. |
|---|
| 25 | </dd> |
|---|
| 26 | </dl> |
|---|
| 27 | <h4>Remarks</h4> |
|---|
| 28 | <div> |
|---|
| 29 | If both <i>x</i> and <i>y</i> are <i>1</i>, this macro expands to <i>1</i>. |
|---|
| 30 | Otherwise, it expands to <i>0</i>. |
|---|
| 31 | </div> |
|---|
| 32 | <div> |
|---|
| 33 | This macro <i>does not</i> perform a boolean conversion on either operand before performing the bitwise <i>AND</i> operation. |
|---|
| 34 | If that conversion is necessary, use <b>BOOST_PP_AND</b> instead. |
