I have tested that added the include fixes the problem. </p> <p> As a workaround, including &lt;cmath&gt; before &lt;.../weighted_p_square_quantile.hpp&gt; in your own source fixes the problem. </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/5894 Trac 1.4.3 Eric Niebler Tue, 13 Sep 2011 15:35:13 GMT https://svn.boost.org/trac10/ticket/5894#comment:1 https://svn.boost.org/trac10/ticket/5894#comment:1 <ul> <li><strong>status</strong> <span class="trac-field-old">new</span> → <span class="trac-field-new">closed</span> </li> <li><strong>resolution</strong> → <span class="trac-field-new">fixed</span> </li> </ul> <p> (In <a class="changeset" href="https://svn.boost.org/trac10/changeset/74367" title="merged [74366] from trunk, fixes #5894">[74367]</a>) merged <a class="changeset" href="https://svn.boost.org/trac10/changeset/74366" title="add missing &lt;cmath&gt; include">[74366]</a> from trunk, fixes <a class="closed ticket" href="https://svn.boost.org/trac10/ticket/5894" title="#5894: Bugs: Missing &lt;cmath&gt; include for weighted_p_square_quantile (closed: fixed)">#5894</a> </p> Ticket
