8 The <b>BOOST_PP_NOT_EQUAL</b> macro compares two values for inequality.
9 </div>
10 <h4>Usage</h4>
11 <div class="code">
12 <b>BOOST_PP_NOT_EQUAL</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 comparison.&nbsp;
19 Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_MAG</b>.
20 </dd>
21 <dt>y</dt>
22 <dd>
23 The right operand of the comparison.&nbsp;
24 Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_MAG</b>.
25 </dd>
26 </dl>
27 <h4>Remarks</h4>
28 <div>
29 If <i>x</i> is equal to <i>y</i>, this macro expands to <i>0</i>.&nbsp;
30 Otherwise, it expands to <i>1</i>.
31 </div>
32 <div>
33 Previously, this macro could not be used inside <b>BOOST_PP_WHILE</b>.&nbsp;
34 There is no longer any such restriction because this macro no longer uses <b>BOOST_PP_WHILE</b>.
