+
+    <p>Pointers to polymorphic objects (objects of classes which define at
+    least one virtual function) are sometimes downcast or crosscast.
+    Downcasting means casting from a base class to a derived class.
+    Crosscasting means casting across an inheritance hierarchy diagram, such
+    as from one base to the other in a <code>Y</code> diagram hierarchy.</p>
+
+    <p>Such casts can be done with old-style casts, but this approach is
+    never to be recommended. Old-style casts are sorely lacking in type
+    safety, suffer poor readability, and are difficult to locate with search
+    tools.</p>
+
+    <p>The C++ built-in <code>static_cast</code> can be used for efficiently
+    downcasting pointers to polymorphic objects, but provides no error
+    detection for the case where the pointer being cast actually points to
+    the wrong derived class. The <code>polymorphic_downcast</code> template retains
+    the efficiency of <code>static_cast</code> for non-debug compilations, but for
+    debug compilations adds safety via an assert() that a <code>dynamic_cast</code>
+    succeeds.</p>
+
+    <p>The C++ built-in <code>dynamic_cast</code> can be used for downcasts and
+    crosscasts of pointers to polymorphic objects, but error notification in
+    the form of a returned value of 0 is inconvenient to test, or worse yet,
+    easy to forget to test. The throwing form of <code>dynamic_cast</code>, which
+    works on references, can be used on pointers through the ugly expression
+    &amp;<code>dynamic_cast&lt;T&amp;&gt;(*p)</code>, which causes undefined
+    behavior if <code>p</code> is <code>0</code>. The <code>polymorphic_cast</code>
+    template performs a <code>dynamic_cast</code> on a pointer, and throws an
+    exception if the <code>dynamic_cast</code> returns 0.</p>
+
+    <p>A <code>polymorphic_downcast</code> should be used for
+    downcasts that you are certain should succeed.  Error checking is
+    only performed in translation units where <code>NDEBUG</code> is
+    not defined, via
+<pre>  assert( dynamic_cast&lt;Derived&gt;(x) == x )
+</pre> where <code>x</code> is the source pointer.  This approach
+    ensures that not only is a non-zero pointer returned, but also
+    that it is correct in the presence of multiple inheritance.
+    Attempts to crosscast using <code>polymorphic_downcast</code> will
+    fail to compile.
+    <b>Warning:</b> Because <code>polymorphic_downcast</code> uses assert(), it
+    violates the One Definition Rule (ODR) if NDEBUG is inconsistently
+    defined across translation units. [See ISO Std 3.2]
+</p><p>
+    For crosscasts, or when the success of a cast can only be known at
+    runtime, or when efficiency is not important,
+    <code>polymorphic_cast</code> is preferred. </p>
+
+    <p>The C++ built-in <code>dynamic_cast</code> must be used to cast references
+    rather than pointers. It is also the only cast that can be used to check
+    whether a given interface is supported; in that case a return of 0 isn't
+    an error condition.</p>

-Sometimes a value must be converted to a literal text form, such as an
-<code>int</code> represented as a <code>string</code>, or vice-versa, when
-a <code>string</code> is interpreted as an <code>int</code>. Such examples
-are common when converting between data types internal to a program and
-representation external to a program, such as windows and configuration files.
-<p>
-The standard C and C++ libraries offer a number of facilities for performing
-such conversions. However, they vary with their ease of use, extensibility,
-and safety.
-<p>
-For instance, there are a number of limitations with the family of standard C
-functions typified by <code>atoi</code>:
-<ul>
-	<li>
-	    Conversion is supported in one direction only: from text to
-		internal data type. Converting the other way using the C library
-		requires either the inconvenience and compromised safety of the
-		<code>sprintf</code> function, or the loss of portability associated
-		with non-standard functions such as <code>itoa</code>.
-	</li>
-	<li>
-	    The range of types supported is only a subset of the built-in numeric
-	    types, namely <code>int</code>, <code>long</code>,
-		and <code>double</code>.
-	</li>
-	<li>
-	    The range of types cannot be extended in a uniform manner. For
-	    instance, conversion from string representation to
-		<code>complex</code> or <code>rational</code>.
-	</li>
-</ul>
-The standard C functions typified by <code>strtol</code> have the same basic
-limitations, but offer finer control over the conversion process. However, for
-the common case such control is often either not required or not used. The
-<code>scanf</code> family of functions offer even greater control, but also
-lack safety and ease of use.
-<p>
-The standard C++ library offers <code>stringstream</code> for the kind of
-in-core formatting being discussed. It offers a great deal of control over the
-formatting and conversion of I/O to and from arbitrary types through text.
-However, for simple conversions direct use of <code>stringstream</code> can be
-either clumsy (with the introduction of extra local variables and the loss of
-infix-expression convenience) or obscure (where <code>stringstream</code>
-objects are created as temporary objects in an expression). Facets provide a
-comprehensive concept and facility for controlling textual representation, but
-their relatively high entry level requires an extreme degree of involvement
-for simple conversions.
-<p>
-The <code>lexical_cast</code> template function offers a convenient and consistent
-form for supporting common conversions to and from arbitrary types when they are
-represented as text. The simplification it offers is in expression-level
-convenience for such conversions. For more involved conversions, such as where
-precision or formatting need tighter control than is offered by the default
-behavior of <code>lexical_cast</code>, the conventional
-<code>stringstream</code> approach is recommended. Where the conversions are
-numeric to numeric, <code><a href="cast.htm#numeric_cast">numeric_cast</a></code>
-may offer more reasonable behavior than <code>lexical_cast</code>.

-For a good discussion of the options and issues involved in string-based formatting,
-including comparison of <code>stringstream</code>, <code>lexical_cast</code>, and
-others, see Herb Sutter's article, <a href="http://www.gotw.ca/publications/mill19.htm">

+    Lexical conversion to these types is simply reading a byte from source but since the source has

+    <p> Q: What does <code>lexical_cast&lt;std::string&gt;</code> of an <code>int8_t</code> or <code>uint8_t</code> not do what I expect?
+    <br> A: As above, note that <code>int8_t</code> and <code>uint8_t</code> are actually chars and are formatted as such.  To avoid this, cast to an integer type first:

-To date the code and test harness have been compiled successfully using
-Microsoft Visual C++ 6.0, Borland C++ 5.5, and GNU g++ 2.91. Tests have run successfully for
-Microsoft Visual C++ 6.0 and Borland C++ 5.5. For g++ streams interpret any integer, rather than
-just <code>0</code> and <code>1</code>, as valid for <code>bool</code>; the other tests pass
-without problem. The deprecated standard header <code>&lt;strstream&gt;</code> is used in
-preference to the standard <code>&lt;sstream&gt;</code> header for out-of-the-box g++ support.

-<h2><a name="future">Future directions</a></h2>
-
-<ul>
-    <li>
-	Improved string handling, correctly accommodating wide character strings, incompatible
-	<code>basic_string</code> types, and empty strings.
-    </li>
-    <li>
-	Optimize the use of a stream away for identity conversions.
-    </li>
-    <li>
-        An <code>interpret_cast</code> that performs a <i>do-something-reasonable</i> conversion between
-        types. It would, for instance, select between <code>numeric_cast</code> and <code>lexical_cast</code>
-        based on <code>std::numeric_limits&lt;&gt;::is_specialized</code>. This would be an interesting
-	project, but there are no concrete plans to pursue this at the moment.
-    </li>
-    <li>
-        It is also worth mentioning future <i>non-directions</i>: anything that involves adding extra
-	arguments for a conversion operation is not being considered. A custom keyword cast, such as
-	<code>lexical_cast</code>, is intended to look like a built-in cast operator: built-in cast operators
-	take only a single operand. Where a higher degree of control is required over conversions, the
-	standard <code>stringstream</code> offers a more appropriate path. Where non-stream-based conversions
-	are required, <code>lexical_cast</code> is the wrong tool for the job, and so it won't be special-cased
-	for such scenarios.
-    </li>
+    <p> Q: The implementation always resets the <code>ios_base::skipws</code> flag of an underlying stream object. It breaks my <code>operator&gt;&gt;</code> that works only in presence of this flag. Can you remove code that resets the flag?
+    <br> A: May be in a future version. There is no requirement in <a href="#n1973">[N1973]</a> to reset the flag but remember that <a href="#n1973">[N1973]</a> is not yet accepted by the committee. By the way, it's a great opportunity to make your <code>operator&gt;&gt;</code> conform to the standard. Read a good C++ book, study <code>std::sentry</code> and <a href="../../libs/io/doc/ios_state.html">ios_state_saver</a>.

+  <li>The previous version of <code>lexical_cast</code> used the default stream 
+    precision for reading and writing floating-point numbers. For numerics that 
+    have a corresponding specialization of <code>std::numeric_limits</code>, the 
+    current version now chooses a precision to match. <br>
+  <li>The previous version of <code>lexical_cast</code> did not support conversion 
+    to or from any wide-character-based types. For compilers with full language 
+    and library support for wide characters, <code>lexical_cast</code> now supports 
+    conversions from <code>wchar_t</code>, <code>wchar_t *</code>, and <code>std::wstring</code> 
+    and to <code>wchar_t</code> and <code>std::wstring</code>. <br>
+  <li>The previous version of <code>lexical_cast</code> assumed that the conventional 
+    stream extractor operators were sufficient for reading values. However, string 
+    I/O is asymmetric, with the result that spaces play the role of I/O separators 
+    rather than string content. The current version fixes this error for <code>std::string</code> 
+    and, where supported, <code>std::wstring</code>: <code>lexical_cast&lt;std::string&gt;("Hello, 
+    World")</code> succeeds instead of failing with a <code>bad_lexical_cast</code> 
+    exception. <br>
+  <li>The previous version of <code>lexical_cast</code> allowed unsafe and meaningless 
+    conversions to pointers. The current version now throws a <code>bad_lexical_cast</code> 
+    for conversions to pointers: <code>lexical_cast&lt;char *&gt;("Goodbye, World")</code> 
+    now throws an exception instead of causing undefined behavior.
