8 The <b>BOOST_PP_MAX</b> macro expands to the greater of its two arguments.
9 </div>
10 <h4>Usage</h4>
11 <div class="code">
12 <b>BOOST_PP_MAX</b>(<i>x</i>, <i>y</i>)
13 </div>
14 <h4>Arguments</h4>
15 <dl>
16 <dt>x</dt>
17 <dd>
18 The first operand.&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 second operand.&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 This macro returns the greater of its two arguments or the value of both arguments if they are equal.
30 </div>
31 <div>
32 Previously, this macro could not be used inside <b>BOOST_PP_WHILE</b>.&nbsp;
33 There is no longer any such restriction.&nbsp;
34 It is more efficient, however, to use <b>BOOST_PP_MAX_D</b> in such a situation.
