+[def __proposalshort__ [@http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2006/n1973.html Lexical Conversion Library Proposal for TR2, N1973]]
+
+[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 Synopsis]
+Library features defined in [@boost:boost/lexical_cast.hpp boost/lexical_cast.hpp]:
+``
+ namespace boost
+ {
+ class bad_lexical_cast;
+
+ template<typename Target, typename Source>
+ Target lexical_cast(const Source& arg);
+
+ template <typename Target>
+ Target lexical_cast(const AnyCharacterType* chars, std::size_t count);
+
+ namespace conversion
+ {
+ template<typename Target, typename Source>
+ bool try_lexical_convert(const Source& arg, Target& result);
+
+ template <typename AnyCharacterType, typename Target>
+ bool try_lexical_convert(const AnyCharacterType* chars, std::size_t count, Target& result);
+
+ } // namespace conversion
+ } // namespace boost
+``
+
+[section lexical_cast]
+``
+ 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.
+
+``
+ template <typename Target>
+ Target lexical_cast(const AnyCharacterType* chars, std::size_t count);
+``
+Takes an array of `count` characters as input parameter and streams them out as a Target object. If the conversion is unsuccessful, a `bad_lexical_cast` exception is thrown. This call may be useful for processing nonzero terminated array of characters or processing just some part of character array.
+
+The requirements on the argument and result types for both functions 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`. Following types also can use `char16_t` or `char32_t` for wide-character streaming:
+
+* Single character: `char16_t`, `char32_t`
+* Arrays of characters: `char16_t *`, `char32_t *`, `const char16_t *`, `const char32_t *`
+* Strings: `std::basic_string`, `boost::containers::basic_string`
+* `boost::iterator_range<WideCharPtr>`, where `WideCharPtr` is a pointer to wide-character or pointer to const wide-character
+* `boost::array<CharT, N>` and `std::array<CharT, N>`, `boost::array<const CharT, N>` and `std::array<const CharT, N>`
+
+[important Many compilers and runtime libraries fail to make conversions using new Unicode characters. Make sure that the following code compiles and outputs nonzero values, before using new types:
+``
+ std::cout
+ << boost::lexical_cast<std::u32string>(1.0).size()
+ << " "
+ << boost::lexical_cast<std::u16string>(1.0).size();
+``
+]
+
+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.
+[endsect]
+
+[section bad_lexical_cast]
+``
+ class bad_lexical_cast : public std::bad_cast
+ {
+ public:
+ ... // same member function interface as std::exception
+ };
+``
+Exception used to indicate runtime lexical_cast failure.
+[endsect]
+
+[section try_lexical_convert]
+`boost::lexical_cast` remains the main interface for lexical conversions. It must be used by default in most cases. However
+some developers wish to make their own conversion functions, reusing all the optimizations of the `boost::lexical_cast`.
+That's where the `boost::conversion::try_lexical_convert` function steps in.
+
+`try_lexical_convert` returns `true` if conversion succeeded, otherwise returns `false`. If conversion
+failed and `false` was returned, state of `result` output variable is undefined.
+
+Actually, `boost::lexical_cast` is implemented using `try_lexical_convert`:
+``
+ template <typename Target, typename Source>
+ inline Target lexical_cast(const Source &arg)
+ {
+ Target result;
+
+ if (!conversion::try_lexical_convert(arg, result))
+ throw bad_lexical_cast();
+
+ return result;
+ }
+``
+
+`try_lexical_convert` relaxes the CopyConstructible and DefaultConstructible requirements for `Target` type.
+Following requirements for `Target` and `Source` remain:
+
+* Source must be 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 must be 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.

+[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>>` more general.
+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.

+
+* [*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.
+
+[pre
+]
+
+* [*Question:] Why `boost::lexical_cast<double>("-1.#IND");` throws `boost::bad_lexical_cast`?
+ * [*Answer:] `"-1.#IND"` is a compiler extension, that violates standard. You shall input `"-nan"`, `"nan"`, `"inf"`
+, `"-inf"` (case insensitive) strings to get NaN and Inf values. `boost::lexical_cast<string>` outputs `"-nan"`, `"nan"`,
+`"inf"`, `"-inf"` strings, when has NaN or Inf input values.
+
+[pre
+]
+
+* [*Question:] What is the fastest way to convert a non zero terminated string or a substring using `boost::lexical_cast`?
+ * [*Answer:] Use `boost::iterator_range` for conversion or `lexical_cast` overload with two parameters. For example, if you whant to convert to `int` two characters from a string `str`, you shall write `lexical_cast<int>(make_iterator_range(str.data(), str.data() + 2));` or `lexical_cast<int>(str.data(), 2);`.

+
+[section Changes]
+
+* [*boost 1.56.0 :]
+
+ * Added `boost::conversion::try_lexical_convert` functions.
+
+* [*boost 1.54.0 :]
+
+ * Fix some issues with `boost::int128_type` and `boost::uint128_type` conversions. Notify user at compile time
+ if the `std::numeric_limits` are not specialized for 128bit types and `boost::lexical_cast` can not make conversions.
+
+* [*boost 1.54.0 :]
+
+ * Added code to convert `boost::int128_type` and `boost::uint128_type` types (requires GCC 4.7 or higher).
+ * Conversions to pointers will now fail to compile, instead of throwing at runtime.
+ * Restored ability to get pointers to `lexical_cast` function (was broken in 1.53.0).
+
+* [*boost 1.53.0 :]
+
+ * Much better input and output streams detection for user defined types.
+
+* [*boost 1.52.0 :]
+
+ * Restored compilation on MSVC-2003 (was broken in 1.51.0).
+ * Added `lexical_cast(const CharType* chars, std::size_t count)` function overload.
+
+* [*boost 1.51.0 :]
+
+ * Better performance, less memory usage for `boost::array<character_type, N>` and `std::array<character_type, N>` conversions.
+
+* [*boost 1.50.0 :]
+
+ * `boost::bad_lexical_cast` exception is now globaly visible and can be catched even if code is compiled with -fvisibility=hidden.
+ * Now it is possible to compile library with disabled exceptions.
+ * Better performance, less memory usage and bugfixes for `boost::iterator_range<character_type*>` conversions.
+
+* [*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 with construction]
+ [``
+ std::stringstream ss;
+ ss << _in;
+ if (ss.fail()) throw std::logic_error(descr);
+ ss >> _out;
+ if (ss.fail()) throw std::logic_error(descr);
+ ``]
+ ]
+[[std::stringstream without construction]
+ [``
+ ss << _in; // ss is an instance of std::stringstream
+ 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.
