7 | <div style="margin-left: 0px;"> | |
8 | The <b>BOOST_PP_EQUAL_D</b> macro compares two values for equality. | |
9 | </div> | |
10 | <h4>Usage</h4> | |
11 | <div class="code"> | |
12 | <b>BOOST_PP_EQUAL_D</b>(<i>d</i>, <i>x</i>, <i>y</i>) | |
13 | </div> | |
14 | <h4>Arguments</h4> | |
15 | <dl> | |
16 | <dt>d</dt> | |
17 | <dd> | |
18 | This argument is ignored. | |
19 | </dd> | |
20 | <dt>x</dt> | |
21 | <dd> | |
22 | The left operand of the comparison. | |
23 | Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_MAG</b>. | |
24 | </dd> | |
25 | <dt>y</dt> | |
26 | <dd> | |
27 | The right operand of the comparison. | |
28 | Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_MAG</b>. | |
29 | </dd> | |
30 | </dl> | |
31 | <h4>Remarks</h4> | |
32 | <div> | |
33 | If <i>x</i> is equal to <i>y</i>, this macro expands to <i>1</i>. | |
34 | Otherwise, it expands to <i>0</i>. | |
35 | </div> | |
36 | <div> | |
37 | This macro is deprecated. | |
38 | It only exists for backward compatibility. | |
39 | Use <b>BOOST_PP_EQUAL</b> instead. | |
