<p><strong>Implementation Note</strong><br>
|

When <code>Bits</code> is the exact size of a built-in unsigned type,
|
||||
the implementation has to change to prevent undefined behavior.
|
||||
Therefore, there are specializations of <code>low_bits_mask_t</code> at
|
||||
those bit counts.</p>

<h2><a name="demo">Demonstration Program</a></h2>
|
||||
|
||||
<p>The program <a href="../test/integer_mask_test.cpp">integer_mask_test.cpp</a>
|
||||
is a simplistic demonstration of the results from instantiating various
|
||||
examples of the bit mask class templates.</p>
|
||||
|
||||
<h2><a name="rationale">Rationale</a></h2>
|
||||
|
||||
<p>The class templates in this header are an extension of the <a
|
||||
href="../integer.htm">integer type selection class templates</a>. The new
|
||||
class templates provide the same sized types, but also convienent masks
|
||||
to use when extracting the highest or all the significant bits when the
|
||||
containing built-in type contains more bits. This prevents
|
||||
contaimination of values by the higher, unused bits.</p>

<h2><a name="usage">Usage</a></h2>

||||
|
||||
|
||||
<p>The <code>boost::static_log2</code> class template takes one template
|
||||
parameter, a value of type <code>static_log2_argument_type</code>. The template
|
||||
only defines one member, <code>value</code>, which gives the truncated
|
||||
base-two logarithm of the template argument.</p>
|
||||
|
||||
<p>Since the logarithm of zero, for any base, is undefined, there is a
|
||||
specialization of <code>static_log2</code> for a template argument
|
||||
of zero. This specialization has no members, so an attempt to use
|
||||
the base-two logarithm of zero results in a compile-time error.</p>
|
||||
|
||||
<p>Note: <ul>
|
||||
|
||||
<li><code>static_log2_argument_type</code> is an <i>unsigned integer

<p>The program <a href="../test/static_log2_test.cpp">static_log2_test.cpp</a>
|
||||
is a simplistic demonstration of the results from instantiating various
|
||||
examples of the binary logarithm class template.</p>

|
||||
<h2><a name="rationale">Rationale</a></h2>
|
||||
|
||||
|
||||
|
||||
<p>The base-two (binary) logarithm, abbreviated <dfn>lb</dfn>, function
|
||||
is occasionally used to give order-estimates of computer algorithms.
|
||||
The truncated logarithm can be considered the highest power-of-two in a
|
||||
value, which corresponds to the value's highest set bit (for binary
|
||||
integers). Sometimes the highest-bit position could be used in generic
|
||||
programming, which requires the position to be statically (<i>i.e.</i>
|
||||
at compile-time) available.</p>

<h2><a name="whatsnew">Changes from previous versions:</a></h2>
|
||||
|
||||
|
||||
|
||||
<ul>
|
||||
<li><i>New in version 1.32.0:</i><br><br>
|
||||
|
||||
The argument type and the result type of <code>boost::static_log2</code>
|
||||
are now typedef'd. Formerly, they were hardcoded as <code>unsigned long</code>
|
||||
and <code>int</code> respectively. Please, use the provided typedefs in new
|
||||
code (and update old code as soon as possible).

|

<p>The original version of the Boost binary logarithm class template was
|
||||
written by <a href="http://www.boost.org/people/daryle_walker.html">Daryle Walker</a>
|
||||
and then enhanced by Giovanni Bajo with support for compilers without
|
||||
partial template specialization. The current version was suggested,
|
||||
together with a reference implementation, by Vesa Karvonen. Gennaro Prota
|
||||
wrote the actual source file.

<h2><a name="usage">Usage</a></h2>
|

<p>The four class templates provide the combinations for finding the

minimum or maximum of two signed or <code>unsigned</code>
|

(<code>long</code>) parameters, <var>Value1</var> and <var>Value2</var>,
|

at compile-time. Each template has a single static data member,
|
||||
<code>value</code>, which is set to the respective minimum or maximum
|
||||
of the template's parameters.</p>

<h2>Rationale</h2>
|
||||
<p>The organization of boost integer headers and classes is designed to take
|
||||
advantage of <code><stdint.h></code> types from in 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 the
|
||||
global namespace or 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/stdint.h></code> and <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. An
|
||||
exception is <code><boost/stdint.h> </code>which uses a <b> .h</b> extension to indicate its C rather than C++ heritage.</p>
|
||||
<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>[Templates to select type based on maximum value are under development.]

</p>
|

|

<p>The <code>int_fast_t</code> class template maps its input type to the
|
||||
next-largest type that the processor can manipulate the easiest, or to
|
||||
itself if the input type is already an easy-to-manipulate type. For
|
||||
instance, processing a bunch of <code>char</code> objects may go faster
|
||||
if they were converted to <code>int</code> objects before processing.
|
||||
The input type, passed as the only template parameter, must be a
|
||||
built-in integral type, except <code>bool</code>. Unsigned integral
|
||||
types can be used, as well as signed integral types, despite the name.
|
||||
The output type is given as the class member <code>fast</code>.</p>
|
||||
<h2>Example</h2>
|
||||
|
||||
<p><strong>Implementation Notes</strong><br>
|
||||
By default, the output type is identical to the input type. Eventually,
|
||||
this code's implementation should be conditionalized for each platform
|
||||
to give accurate mappings between the built-in types and the
|
||||
easiest-to-manipulate built-in types. Also, there is no guarantee that
|
||||
the output type actually is easier to manipulate than the input
|
||||
type.</p>
