<h1><img src="../../c++boost.gif" alt="c++boost.gif (8819 bytes)" align="center" width="277" height="86">Header
|
||||
boost/cstdint.hpp </h1>
|
||||
<p>The header <code><a href="../../boost/cstdint.hpp"><boost/cstdint.hpp></a></code>
|
||||
provides the typedef's useful for
|
||||
writing portable code that requires certain integer widths. All typedef's are in namespace boost.</p>
|
||||
<p>The specifications are based on the ISO/IEC 9899:1999 C Language standard
|
||||
header <stdint.h>. The 64-bit types required by the C standard are not
|
||||
required in the boost header, and may not be supplied in all implementations,
|
||||
because <code>long long</code> is not [yet] included in the C++ standard.</p>
|
||||
<p>See <a href="cstdint_test.cpp">cstdint_test.cpp</a> for a test program.</p>
|
||||
<h2>Exact-width integer types</h2>
|
||||
<p>The typedef <code>int#_t</code>, with # replaced by the width, designates a
|
||||
signed integer type of exactly # bits; <code>int8_t</code> denotes an 8-bit
|
||||
signed integer type. Similarly, the typedef <code>uint#_t</code>
|
||||
designates and unsigned integer type of exactly # bits.</p>
|
||||
<p>These types are optional. However, if an implementation provides integer
|
||||
types with widths of 8, 16, 32, or 64 bits, it shall define the corresponding
|
||||
typedef names.</p>
|
||||
<h2>Minimum-width integer types</h2>
|
||||
<p>The typedef <code>int_least#_t</code>, with # replaced by the width,
|
||||
designates a signed integer type with a width of at least # bits, such that no
|
||||
signed integer type with lesser size has at least the specified width. Thus, <code>int_least32_t</code>
|
||||
denotes a signed integer type with a width of at least 32 bits. Similarly, the
|
||||
typedef name <code>uint_least#_t</code> designates an unsigned integer type with
|
||||
a width of at least # bits, such that no unsigned integer type with lesser size
|
||||
has at least the specified width.</p>
|
||||
<p>Required minimum-width integer types:</p>
|
||||
<ul>
|
||||
<li><code>int_least8_t</code></li>
|
||||
<li><code>int_least16_t</code></li>
|
||||
<li><code>int_least32_t</code></li>
|
||||
<li><code>uint_least8_t</code></li>
|
||||
<li><code>uint_least16_t</code></li>
|
||||
<li><code>uint_least32_t</code></li>
|
||||
</ul>
|
||||
<p>All other minimum-width integer types are optional.</p>
|
||||
<h2>Fastest minimum-width integer types</h2>
|
||||
<p>The typedef <code>int_fast#_t</code>, with # replaced by the width,
|
||||
designates the fastest signed integer type with a width of at least # bits.
|
||||
Similarly, the typedef name <code>uint_fast#_t</code> designates the fastest
|
||||
unsigned integer type with a width of at least # bits.</p>
|
||||
<p>There is no guarantee that these types are fastest for all purposes. In
|
||||
any case, however, they satisfy the signedness and width requirements.</p>
|
||||
<p>Required fastest minimum-width integer types:</p>
|
||||
<ul>
|
||||
<li><code>int_fast8_t</code></li>
|
||||
<li><code>int_fast16_t</code></li>
|
||||
<li><code>int_fast32_t</code></li>
|
||||
<li><code>uint_fast8_t</code></li>
|
||||
<li><code>uint_fast16_t</code></li>
|
||||
<li><code>uint_fast32_t</code></li>
|
||||
</ul>
|
||||
<p>All other fastest minimum-width integer types are optional.</p>
|
||||
<h2>Greatest-width integer types</h2>
|
||||
<p>The typedef <code>intmax_t </code>designates a signed integer type capable of
|
||||
representing any value of any signed integer type.</p>
|
||||
<p>The typedef <code>uintmax_t</code> designates an unsigned integer type
|
||||
capable of representing any value of any unsigned integer type.</p>
|
||||
<p>These types are required.</p>

|

// NOTE OF OBSOLESCENCE: In general, this header file cannot detect
|

// whether the current translation unit somewhere includes ISO C99
|

// <stdint.h> or not. For example, in case BOOST_HAS_STDINT_H
|

// is not defined and ISO C99 <stdint.h> has been included before,
|

// this file will re-define ISO C99 reserved file-scope identifiers
|

// such as int8_t (see ISO C99 7.1.3 and 7.18). Defining the macro
|
||||
// BOOST_HAS_STDINT_H is not sufficient in general, in
|
||||
// particular if a partly conformant <stdint.h> header is available
|
||||
// on the platform, e.g. Comeau C++ with GNU glibc 2.1.2.
|

//
|
||||
// In order to avoid incompatibilities with ISO C99, this header
|

// should not be used at all, and it may be deleted in the future.
|

// C++ programs which require ISO C99 <stdint.h> functionality are
|

// strongly advised to use <boost/cstdint.hpp> instead, which

<h2>Rationale</h2>
|
||||
<p>The organization of boost integer headers and classes is designed to take
|
||||
advantage of <code><stdint.h></code> types from the 1999 C standard
|
||||
without resorting to undefined behavior in terms of
|
||||
the 1998 C++ standard. The header <code><boost/cstdint.hpp></code>
|
||||
makes the standard integer types safely available in namespace boost without placing any names in namespace std. As always, the intension is to complement rather than
|
||||
compete with the C++ Standard Library. Should some future C++ standard
|
||||
include <code><stdint.h></code> and <code><cstdint></code>, then <code><boost/cstdint.hpp></code>
|
||||
will continue to function, but will become redundant and may be safely deprecated.</p>
|
||||
<p>Because these are boost headers, their names conform to boost header naming
|
||||
conventions rather than C++ Standard Library header naming conventions.
|
||||
|
||||
<h2>Caveat emptor</h2>
|
||||
<p>As an
|
||||
implementation artifact, certain C <limits.h> macro names may possibly be
|
||||
visible to users of <boost/cstdint.hpp>. Don't use these macros; they are not part of
|
||||
any Boost specified interface.
|
||||
Use boost:: integer_traits<> or std::numeric_limits<> instead.</p>
|
||||
|
||||
<p>
|
||||
As another implementation artifact, certain C
|
||||
<code><stdint.h></code> typedef names may possibly be visible in the
|
||||
global namespace to users of <code><boost/cstdint.hpp></code>.
|
||||
Don't use these names, they are not part of any Boost specified
|
||||
interface. Use the respective names in namespace <code>boost</code>
|
||||
instead.

<h1><img src="../../c++boost.gif" alt="c++boost.gif (8819 bytes)" align="center" width="277" height="86">Integer
|
||||
Type Selection Templates</h1>
|
||||
<p>The <code><a href="../../boost/integer.hpp"><boost/integer.hpp></a></code>
|
||||
type selection templates allow integer types to be selected based on desired
|
||||
characteristics such as number of bits or maximum value. This facility is
|
||||
particularly useful for solving generic programming problems.</p>
|
||||
|
||||
<p>The templates <b>int_t<></b> and <b>uint_t<></b> supply typedefs <b>least</b>
|
||||
and <b>fast</b>. The <b>least</b> type be the smallest type which holds at
|
||||
least the number of bits (including sign) specified. The <b>fast</b> type will
|
||||
be at least as large as the <b>least</b> type, but may possible be larger.
|
||||
There is no guarantee that the <b>fast</b> type will actually be faster than
|
||||
other possible types.</p>
|
||||
|
||||
<h2>Alternative</h2>
|
||||
|
||||
<p>If the number of bits required is known beforehand, it may be more
|
||||
appropriate to use the types supplied in <code><a href="../../boost/cstdint.hpp"><boost/cstdint.hpp></a></code>.</p>
|
||||
|
||||
<h2>Synopsis</h2>
|
||||
|
||||
<blockquote>
|
||||
<pre>namespace boost
|
||||
{
|
||||
// fast integers from least integers
|
||||
// int_fast_t<> works correctly for unsigned too, in spite of the name.
|
||||
template< typename LeastInt > // Required: LeastInt is integral type, not bool
|
||||
struct int_fast_t { typedef LeastInt fast; }; // implementations may specialize
|
||||
|
||||
// signed
|
||||
template< int Bits > // bits (including sign) required, 0-32 valid
|
||||
struct int_t
|
||||
{
|
||||
typedef <i>implementation-supplied</i> least;
|
||||
typedef int_fast_t<least>::fast fast;
|
||||
};
|
||||
|
||||
// unsigned
|
||||
template< int Bits > // bits required, 0-32 valid
|
||||
struct uint_t
|
||||
{
|
||||
typedef <i>implementation-supplied</i> least;
|
||||
typedef int_fast_t<least>::fast fast;
|
||||
// int_fast_t<> works correctly for unsigned too, in spite of the name.
|
||||
};
|
||||
} // namespace boost
|
||||
</pre>
|
||||
|
||||
</blockquote>
|
||||
<p>[Templates to select type based on maximum value are under development.]
|
||||
</p>
|
||||
|
||||
<h2>Example</h2>
|
||||
|
||||
<blockquote>
|
||||
<pre>#include <boost/integer.hpp>
|
||||
using boost::int_t;
|
||||
|
||||
...
|
||||
int_t<24>::least my_var; </pre>
|
||||
|
||||
</blockquote>
|
||||
<h2>Demonstration Program</h2>
|
||||
|
||||
<p>The program <a href="integer_test.cpp">integer_test.cpp</a> is a not very
|
||||
smart demonstration of the results from instantiating various <b>int_t<></b>
|
||||
and <b>uint_t<></b> examples.</p>
|
||||
|
||||
<h2>Rationale</h2>
|
||||
|
||||
<p>The rationale for the design of the templates in this header includes:</p>
|
||||
|
||||
<ul>
|
||||
<li>Avoid recursion because of concern about C++'s limited guaranteed
|
||||
recursion depth (17).</li>
|
||||
<li>Avoid macros on general principles.</li>
|
||||
<li>Try to keep the design as simple as possible.</li>
|
||||
</ul>
|
||||
|
||||

<h1><img src="../../c++boost.gif" alt="c++boost.gif (8819 bytes)" align="center" width="277" height="86">Compile-Time Integral
|
||||
Type Limits</h1>
|
||||
|
||||
<p>
|
||||
The C++ Standard Library <limits> header supplies a class template
|
||||
numeric_limits<> with specializations for each fundamental
|
||||
type.</p>
|
||||
<p>
|
||||
For integer types, the interesting members of std::numeric_limits<> are:
|
||||
<pre> static const bool is_specialized; // will be true for integers
|
||||
static T min() throw();
|
||||
static T max() throw();
|
||||
static const int digits; // for integers, # value bits
|
||||
static const int digits10;
|
||||
static const bool is_signed;
|
||||
static const bool is_integer; // will be true for integers</pre>
|
||||
For many uses, these are sufficient. But min() and max() are problematical because they are not constant expressions
|
||||
(std::5.19), yet some usages require constant expressions.
|
||||
<p>
|
||||
The template class <code>integer_traits</code> addresses this
|
||||
problem.
|
||||
|
||||
|
||||
<h2>Header <code><a href="../../boost/integer_traits.hpp">integer_traits.hpp</a></code> Synopsis</h2>
|
||||
|
||||
<pre>namespace boost {
|
||||
template<class T>
|
||||
class integer_traits : public std::numeric_limits<T>
|
||||
{
|
||||
static const bool is_integral = false;
|
||||
};
|
||||
|
||||
// specializations for all integral types
|
||||
}</pre>
|
||||
|
||||
|
||||
<h2>Description</h2>
|
||||
|
||||
Template class <code>integer_traits</code> is derived from
|
||||
<code>std::numeric_limits</code>. In general, it adds the single
|
||||
<code>bool</code> member <code>is_integral</code> with the
|
||||
compile-time constant value <code>false</code>. However, for all
|
||||
integral types <code>T</code> (std::3.9.1/7 [basic.fundamental]),
|
||||
there are specializations provided with the following compile-time
|
||||
constants defined:
|
||||
<p>
|
||||
<table border=1>
|
||||
<tr><th>member</th><th>type</th><th>value</th></tr>
|
||||
<tr><td><code>is_integral</code></td><td>bool</td><td><code>true</code></td></tr>
|
||||
<tr><td><code>const_min</code></td><td><code>T</code></td><td>equivalent
|
||||
to <code>std::numeric_limits<T>::min()</code></td></tr>
|
||||
<tr><td><code>const_max</code></td><td><code>T</code></td><td>equivalent
|
||||
to <code>std::numeric_limits<T>::max()</code></td></tr>
|
||||
</table>
|
||||
|
||||
<p>
|
||||
|
||||
<em>Note:</em> A flag <code>is_integral</code> is provided, because a
|
||||
user-defined integer class should specialize
|
||||
<code>std::numeric_limits<>::is_integer = true</code>,
|
||||
nonetheless compile-time constants <code>const_min</code> and
|
||||
<code>const_max</code> cannot be provided for that user-defined class.
|
||||
|
||||
<h2>
|
||||
|
||||
Test Program</h2>
|
||||
|
||||
<p>
|
||||
|
||||
The program <code><a href="integer_traits_test.cpp">integer_traits_test.cpp</a></code>
|
||||
exercises the <code>integer_traits</code> class.
|
||||
|
||||
<h2>Acknowledgements</h2>
|
||||
|
||||
Beman Dawes, Ed Brey, Steve Cleary, and Nathan Myers discussed the integer
|
||||
traits idea on the boost mailing list in August 1999.
