The only standard way to use these functions (pow included) is via std:: namespace. </p> <p> All the uses of pow should be converted to std::pow, otherwise compilers with strictly conforming standard headers (like SunCC) will not be able to compile. </p> <p> std::pow works fine with all the compilers I tried (SunCC, g++). </p> <p> (suggested patch attached) </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/6056 Trac 1.4.3 Fedor Sergeev <Fedor.Sergeev@…> Tue, 25 Oct 2011 11:02:26 GMT https://svn.boost.org/trac10/ticket/6056 https://svn.boost.org/trac10/ticket/6056 <ul> <li><strong>attachment</strong> → <span class="trac-field-new">diffs</span> </li> </ul> <p> patch for std::pow </p> Ticket
