It includes cast-style function templates designed to complement the C++ Standard's built-in casts.</p> <p>To reduce coupling, particularly to standard library IOStreams, the Boost Conversion Library is supplied by several headers:</p> <ul> <li>The <a href="cast.htm">boost/cast</a> header provides <b>polymorphic_cast<></b> and <b>polymorphic_downcast<></b> to perform safe casting between polymorphic types.<br> </li> <li>The <a href="lexical_cast.htm">boost/lexical_cast</a> header provides <b>lexical_cast<></b> general literal text conversions, such as an <code>int</code> represented as a <code>string</code>, or vice-versa.</li> </ul> <hr> <p>Revised <!--webbot bot="Timestamp" S-Type="EDITED" S-Format="%d %B, %Y" startspan -->June 23, 2005<!--webbot bot="Timestamp" endspan i-checksum="30348" --> </p> </body> </html>
