<h1><img src="../../c++boost.gif" alt="c++boost.gif (8819 bytes)" align="center" width="277" height="86">Header
boost/cstdint.hpp&nbsp;</h1>
<p>The header <code><a href="../../boost/cstdint.hpp">&lt;boost/cstdint.hpp&gt;</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 &lt;stdint.h&gt;.&nbsp; 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.&nbsp; 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,&nbsp;
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.&nbsp; In
any case, however, they satisfy&nbsp; 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>

<h2>Rationale</h2>
<p>The organization of boost integer headers and classes is designed to take
advantage of <code>&lt;stdint.h&gt;</code> types from the 1999 C standard
without resorting to undefined behavior in terms of
the 1998 C++ standard.&nbsp; The header <code>&lt;boost/cstdint.hpp&gt;</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.&nbsp; Should some future C++ standard
include <code>&lt;stdint.h&gt;</code> and <code>&lt;cstdint&gt;</code>, then <code>&lt;boost/cstdint.hpp&gt;</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 &lt;limits.h&gt; macro names may possibly be
visible to users of &lt;boost/cstdint.hpp&gt;.&nbsp; Don't use these macros; they are not part of
any Boost specified interface.&nbsp;
Use boost:: integer_traits&lt;&gt; or std::numeric_limits&lt;&gt; instead.</p>
<p>
As another implementation artifact, certain C
<code>&lt;stdint.h&gt;</code> typedef names may possibly be visible in the
global namespace to users of <code>&lt;boost/cstdint.hpp&gt;</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">&lt;boost/integer.hpp&gt;</a></code>
type selection templates allow integer types to be selected based on desired
characteristics such as number of bits or maximum value.&nbsp; This facility is
particularly useful for solving generic programming problems.</p>
<p>The templates <b>int_t&lt;&gt;</b> and <b>uint_t&lt;&gt;</b> supply typedefs <b>least</b>
and <b>fast</b>.&nbsp; 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.&nbsp;
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">&lt;boost/cstdint.hpp&gt;</a></code>.</p>
<h2>Synopsis</h2>
<blockquote>
<pre>namespace boost
{
// fast integers from least integers
template&lt; typename LeastInt &gt; // Required: LeastInt is integral type, not bool
struct int_fast_t { typedef LeastInt fast; }; // implementations may specialize
// signed
template&lt; int Bits &gt; // bits (including sign) required, 0-32 valid
struct int_t
{
typedef <i>implementation-supplied</i> least;
typedef int_fast_t&lt;least&gt;::fast fast;
};
// unsigned
template&lt; int Bits &gt; // bits required, 0-32 valid
struct uint_t
{
typedef <i>implementation-supplied</i> least;
typedef int_fast_t&lt;least&gt;::fast fast;
};
} // namespace boost
</pre>
</blockquote>
<p>[Templates to select type based on maximum value are under development.]
</p>
<h2>Example</h2>
<blockquote>
<pre>#include &lt;boost/integer.hpp&gt;
using boost::int_t;
...
int_t&lt;24&gt;::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&lt;&gt;</b>
and <b>uint_t&lt;&gt;</b> examples.</p>
<h2>Rationale</h2>
<p>The rationale for the design of the templates in this header includes:</p>
<ul>
<li>Avoid&nbsp; 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>

<title>integer_traits: Compile-Time Limits for Integral Types</title>

<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 &lt;limits&gt; header supplies a class template
numeric_limits&lt;&gt; with specializations for each fundamental
type.</p>
<p>
For integer types, the interesting members of std::numeric_limits&lt;&gt; 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&lt;class T&gt;
class integer_traits : public std::numeric_limits&lt;T&gt;
{
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&lt;T&gt;::min()</code></td></tr>
<tr><td><code>const_max</code></td><td><code>T</code></td><td>equivalent
to <code>std::numeric_limits&lt;T&gt;::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&lt;&gt;::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.
