Conversion Library</h1>
<p>The Conversion Library improves program safety and clarity by performing
otherwise messy conversions. 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, and <b> numeric_cast</b><i><></i> to perform safe casting
between numeric 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>
