+
+    <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

+
+[section Motivation]
+Sometimes a value must be converted to a literal text form, such as an [c++] `int` represented as a `std::string`, or vice-versa, when a `std::string` is interpreted as an `int`. 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.
+
+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.
+
+For instance, there are a number of limitations with the family of standard C functions typified by `atoi`:
+
+* 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 `sprintf` function, or the loss of portability associated with non-standard functions such as `itoa`.
+* The range of types supported is only a subset of the built-in numeric types, namely `int`, `long`, and `double`.
+* The range of types cannot be extended in a uniform manner. For instance, conversion from string representation to complex or rational.
+
+The standard C functions typified by `strtol` 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 `scanf` family of functions offer even greater control, but also lack safety and ease of use.
+
+The standard C++ library offers `stringstream` 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 `stringstream` can be either clumsy (with the introduction of extra local variables and the loss of infix-expression convenience) or obscure (where `stringstream` objects are created as temporary objects in an expression). Facets provide a comprehensive concept and facility for controlling textual representation, but their perceived complexity and high entry level requires an extreme degree of involvement for simple conversions, and excludes all but a few programmers.
+
+The `lexical_cast` function template 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 `lexical_cast`, the conventional `std::stringstream` approach is recommended. Where the conversions are numeric to numeric, __numericcast__ may offer more reasonable behavior than `lexical_cast`.
+
+For a good discussion of the options and issues involved in string-based formatting, including comparison of `stringstream`, `lexical_cast`, and others, see Herb Sutter's article, [@http://www.gotw.ca/publications/mill19.htm The String Formatters of Manor Farm]. Also, take a look at the [link boost_lexical_cast.performance Performance] section.

+[section Examples]
+The following example treats command line arguments as a sequence of numeric data:
+``
+    int main(int argc, char * argv[])
+    {
+        using boost::lexical_cast;
+        using boost::bad_lexical_cast;
+
+        std::vector<short> args;
+
+        while(*++argv)
+        {
+            try
+            {
+                args.push_back(lexical_cast<short>(*argv));
+            }
+            catch(bad_lexical_cast &)
+            {
+                args.push_back(0);
+            }
+        }
+        ...
+    }
+``
+The following example uses numeric data in a string expression:
+``
+    void log_message(const std::string &);
+
+    void log_errno(int yoko)
+    {
+        log_message("Error " + boost::lexical_cast<std::string>(yoko) + ": " + strerror(yoko));
+    }

+    template<typename Target, typename Source>
+      Target lexical_cast(const Source& arg);
+``
+Returns the result of streaming arg into a standard library string-based stream and then out as a Target object. Where Target is either `std::string` or `std::wstring`, stream extraction takes the whole content of the string, including spaces, rather than relying on the default `operator>>` behavior. If the conversion is unsuccessful, a `bad_lexical_cast` exception is thrown.
+
+The requirements on the argument and result types are:
+
+* Source is OutputStreamable, meaning that an `operator<<` is defined that takes a `std::ostream` or `std::wostream` object on the left hand side and an instance of the argument type on the right.
+* Target is InputStreamable, meaning that an `operator>>` is defined that takes a `std::istream` or `std::wistream` object on the left hand side and an instance of the result type on the right.
+* Target is CopyConstructible [20.1.3].
+* Target is DefaultConstructible, meaning that it is possible to default-initialize an object of that type [8.5, 20.1.4].
+
+The character type of the underlying stream is assumed to be char unless either the Source or the Target requires wide-character streaming, in which case the underlying stream uses `wchar_t`. Source types that require wide-character streaming are `wchar_t`, `wchar_t *`, and `std::wstring`. Target types that require wide-character streaming are `wchar_t` and `std::wstring`.
+
+Where a higher degree of control is required over conversions, `std::stringstream` and `std::wstringstream` offer a more appropriate path. Where non-stream-based conversions are required, `lexical_cast` is the wrong tool for the job and is not special-cased for such scenarios.

+[section Frequently Asked Questions]
+
+* [*Question:]    Why does `lexical_cast<int8_t>("127")` throw `bad_lexical_cast`?
+  * [*Answer:]      The type `int8_t` is a `typedef` to `char` or `signed char`. Lexical conversion to these types is simply reading a byte from source but since the source has more than one byte, the exception is thrown. 
+Please use other integer types such as `int` or `short int`. If bounds checking is important, you can also 
+call __numericcast__: 
+`numeric_cast<int8_t>(lexical_cast<int>("127"));`
+
+[pre
+]
+
+* [*Question:]    Why does `lexical_cast<unsigned char>("127")` throw `bad_lexical_cast`?
+  * [*Answer:]      Lexical conversion to any char type is simply reading a byte from source. But since the source has more than one byte, the exception is thrown. 
+Please use other integer types such as `int` or `short int`. If bounds checking is important, you can also 
+call __numericcast__: 
+`numeric_cast<unsigned char>(lexical_cast<int>("127"));`
+
+[pre
+]
+
+* [*Question:]    What does `lexical_cast<std::string>` of an `int8_t` or `uint8_t` not do what I expect?
+  * [*Answer:]      As above, note that int8_t and uint8_t are actually chars and are formatted as such. To avoid 
+this, cast to an integer type first: `lexical_cast<std::string>(static_cast<int>(n));`
+
+[pre
+]
+
+* [*Question:]    The implementation always resets the `ios_base::skipws` flag of an underlying stream object. 
+It breaks my `operator>>` that works only in presence of this flag. Can you remove code that resets the flag?
+  * [*Answer:]      May be in a future version. There is no requirement in 
+__proposallong__ to reset the flag but 
+remember that __proposalshort__ is not yet accepted by the committee. By the way, it's a great opportunity to 
+make your `operator>>` conform to the standard.
+Read a good C++ book, study `std::sentry` and [@boost:libs/io/doc/ios_state.html `ios_state_saver`].
+
+[pre
+]
+
+* [*Question:]    Why `std::cout << boost::lexical_cast<unsigned int>("-1");` does not throw, but outputs 4294967295?
+  * [*Answer:]      `boost::lexical_cast` has the behavior of `std::stringstream`, which uses `num_get` functions of 
+`std::locale` to convert numbers. If we look at the Programming languages — C++, we'll see, that `num_get` uses 
+the rules of `scanf` for conversions. And in the C99 standard for unsigned input value minus sign is optional, so 
+if a negative number is read, no errors will arise and the result will be the two's complement.
+
+[pre
+]
+
+* [*Question:]    Why `boost::lexical_cast<int>(L'A');` outputs 65 and `boost::lexical_cast<wchar_t>(L"65");` does not throw?
+  * [*Answer:]      If you are using an old version of Visual Studio or compile code with /Zc:wchar_t- flag, 
+`boost::lexical_cast` sees single `wchar_t` character as `unsigned short`. It is not a `boost::lexical_cast` mistake, but a 
+limitation of compiler options that you use.

+
+[section Changes]
+* [*boost 1.49.0 :]
+  
+    * Restored work with typedefed wchar_t (compilation flag /Zc:wchar_t- for Visual Studio). 
+    * Better performance and less memory usage for `boost::container::basic_string` conversions.
+    
+* [*boost 1.48.0 :]
+  
+    * Added code to work with Inf and NaN on any platform.    
+    * Better performance and less memory usage for conversions to float type (and to double type, if `sizeof(double) < sizeof(long double)`).
+  
+* [*boost 1.47.0 :]
+
+    * Optimizations for "C" and other locales without number grouping.
+    * Better performance and less memory usage for unsigned char and signed char conversions.
+    * Better performance and less memory usage for conversions to arithmetic types.
+    * Better performance and less memory usage for conversions from arithmetic type to arithmetic type.
+    * Directly construct Target from Source on some conversions (like conversions from string to string, from char array to string, from char to char and others).
+
+* [*boost 1.34.0 :]
+
+    * Better performance for many combinations of Source and Target types. For more details refer to Alexander Nasonovs article [@http://accu.org/index.php/journals/1375 Fine Tuning for lexical_cast, Overload #74, August 2006] [@http://www.accu.org/var/uploads/journals/overload74.pdf (PDF)].
+
+* [*boost 1.33.0 :]
+
+    * Call-by-const reference for the parameters. This requires partial specialization of class templates, so it doesn't work for MSVC 6, and it uses the original pass by value there.
+    * The MSVC 6 support is deprecated, and will be removed in a future Boost version.
+
+* [*Earlier :]
+
+    * The previous version of lexical_cast used the default stream precision for reading and writing floating-point numbers. For numerics that have a corresponding specialization of `std::numeric_limits`, the current version now chooses a precision to match.
+    * The previous version of lexical_cast did not support conversion to or from any wide-character-based types. For compilers with full language and library support for wide characters, `lexical_cast` now supports conversions from `wchar_t`, `wchar_t *`, and `std::wstring` and to `wchar_t` and `std::wstring`.
+    * The previous version of `lexical_cast` 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 `std::string` and, where supported, `std::wstring`: `lexical_cast<std::string>("Hello, World")` succeeds instead of failing with a `bad_lexical_cast` exception.
+    * The previous version of `lexical_cast` allowed unsafe and meaningless conversions to pointers. The current version now throws a `bad_lexical_cast` for conversions to pointers: `lexical_cast<char *>("Goodbye, World")` now throws an exception instead of causing undefined behavior.

+
+[section Performance]
+
+In most cases `boost::lexical_cast` is faster than `scanf`, `printf`, `std::stringstream`. For more detailed info you can look at the tables below.
+
+[section Tests description]
+All the tests measure execution speed in milliseconds for 10000 iterations of the following code blocks:
+[table:legend Tests source code
+[[Test name] [Code]]
+[[lexical_cast]
+  [``
+            _out = boost::lexical_cast<OUTTYPE>(_in);

+            std::stringstream ss;
+            ss << _in;
+            if (ss.fail()) throw std::logic_error(descr);
+            ss >> _out;
+            if (ss.fail()) throw std::logic_error(descr);

+            ss >> _out;
+            if (ss.fail()) throw std::logic_error(descr);
+            /* reseting std::stringstream to use it again */
+            ss.str(std::string());
+            ss.clear();
+  ``]
+  ]
+[[scanf/printf]
+  [``
+            typename OUTTYPE::value_type buffer[500];
+            sprintf( (char*)buffer, conv, _in);
+            _out = buffer;
+  ``]
+  ]
+]
+Fastest results are highlitened with "!!! *x* !!!". 
+Do not use this results to compare compilers, because tests were taken on different hardware.

-<h2><a name="motivation">Motivation</a></h2>
-
-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>.
-<p>

-<h2><a name="examples">Examples</a></h2>
-
-The following example treats command line arguments as a sequence of numeric data:
-<blockquote>
-<pre>
-int main(int argc, char * argv[])
-{
-    using boost::lexical_cast;
-    using boost::bad_lexical_cast;
-
-    std::vector&lt;short&gt; args;
-
-    while(*++argv)
-    {
-        try
-        {
-            args.push_back(lexical_cast&lt;short&gt;(*argv));
-        }
-        catch(bad_lexical_cast &amp;)
-        {
-            args.push_back(0);
-        }
-    }
-    ...
-}
-</pre>
-</blockquote>
-
-The following example uses numeric data in a string expression:
-<blockquote>
-<pre>
-void log_message(const std::string &amp;);
-
-void log_errno(int yoko)
-{
-    log_message(&quot;Error &quot; + boost::lexical_cast&lt;std::string&gt;(yoko) + &quot;: &quot; + strerror(yoko));
