+# Boost.Integer
+
+Boost.Integer, part of collection of the [Boost C++ Libraries](https://github.com/boostorg), provides
+integer type support, particularly helpful in generic programming. It provides the means to select
+an integer type based upon its properties, like the number of bits or the maximum supported value,
+as well as compile-time bit mask selection. There is a derivative of `std::numeric_limits` that provides
+integral constant expressions for `min` and `max`...
+Finally, it provides two compile-time algorithms: determining the highest power of two in a
+compile-time value; and computing min and max of constant expressions.

-<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>

+The class and function templates in <boost/math/common_factor.hpp>
+provide run-time and compile-time evaluation of the greatest common divisor
+(GCD) or least common multiple (LCM) of two integers.
+These facilities are useful for many numeric-oriented generic

+
+The boost::integer::gcd function template returns the greatest common
+(nonnegative) divisor of the two integers passed to it.
+`boost::integer::gcd_range` is the iteration of the above gcd algorithm over a
+range, returning the greatest common divisor of all the elements. The algorithm
+terminates when the gcd reaches unity or the end of the range. Thus it also
+returns the iterator after the last element inspected because this may not be
+equal to the end of the range.  The variadic version of `gcd` behaves similarly
+but does not indicate which input value caused the gcd to reach unity.
+
+The boost::integer::lcm function template returns the least common
+(nonnegative) multiple of the two integers passed to it.
+As with gcd, there are range and variadic versions of the function for
+more than 2 arguments.
+
+Note that these functions are constexpr in C++14 and later only.

+
+The type `static_gcd_type` is the widest unsigned-integer-type that is supported
+for use in integral-constant-expressions by the compiler.  Usually this
+the same type as `boost::uintmax_t`, but may fall back to being `unsigned long`
+for some older compilers.
+
+The boost::integer::static_gcd and boost::integer::static_lcm class templates
+take two value-based template parameters of the ['static_gcd_type] type
+and inherit from the type `boost::mpl::integral_c`.
+Inherited from the base class, they have a member /value/
+that is the greatest common factor or least
+common multiple, respectively, of the template arguments.
+A compile-time error will occur if the least common multiple
+is beyond the range of `static_gcd_type`.

+[section:overview Overview]
+
+Boost.Integer provides integer type support, particularly helpful in generic programming.
+It provides the means to select an integer type based upon its properties, like the number of bits or
+the maximum supported value, as well as compile-time bit mask selection.  There is a derivative of
+std::numeric_limits that provides integral constant expressions for `min` and `max`.
+Finally, it provides two compile-time algorithms: determining the highest power of two in a
+compile-time value; and computing min and max of constant expressions.

+[section:traits Integer Traits]
+
+[section Motivation]
+
+The C++ Standard Library <limits> header supplies a class template `numeric_limits<>` with specializations for each fundamental type.
+
+For integer types, the interesting members of `std::numeric_limits<>` are:
+
+   static const bool is_specialized;      // Will be true for integer types.
+   static T min() throw();                // Smallest representable value.
+   static T max() throw();                // Largest representable value.
+   static const int digits;               // For integers, the number of value bits.
+   static const int digits10;             // The number of base 10 digits that can be represented.
+   static const bool is_signed;           // True if the type is signed.
+   static const bool is_integer;          // Will be true for all integer types.
+
+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.
+
+The template class [^integer_traits] addresses this problem.
+
+[endsect]
+
+[section Synopsis]
+
+   namespace boost {
+     template<class T>
+     class integer_traits : public std::numeric_limits<T>
+     {
+     public:
+        static const bool is_integral = false;
+        //
+        // These members are defined only if T is a built-in
+        // integal type:
+        //
+        static const T const_min = ``['implementation-defined]``;
+        static const T const_max = ``['implementation-defined]``;
+     };
+   }
+
+[endsect]
+
+[section Description]
+
+Template class [^integer_traits] is derived from [^std::numeric_limits]. The primary specialization adds the single
+[^bool] member [^is_integral] with the compile-time constant value [^false].
+However, for all integral types [^T] (std::3.9.1/7 [basic.fundamental]), there are specializations
+provided with the following compile-time constants defined:
+
+[table
+   [[member][type][value]]
+   [[[^is_integral]][bool][[^true]]]
+   [[[^const_min]][[^T]][equivalent to [^std::numeric_limits<T>::min()]]]
+   [[[^const_max]][[^T]][equivalent to [^std::numeric_limits<T>::max()]]]
+]
+
+Note: The /is_integral/ flag is provided, because a user-defined integer class should specialize
+[^std::numeric_limits<>::is_integer = true], while compile-time constants
+[^const_min] and [^const_max] are not provided for that user-defined class, unless boost::integer_traits is also specialized.

+
+The [^int_fast_t] 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 [^char] objects may go faster if they were converted to [^int] objects before processing.
+The input type, passed as the only template parameter, must be a built-in integral type, except [^bool].
+Unsigned integral types can be used, as well as signed integral types.
+The output type is given as the nested type [^fast].
+
+[*Implementation Notes:]
+By default, the output type is identical to the input type. Eventually, this code's implementation should
+be customized 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.

+
+[endsect]
+
+[section Usage]
+
+The [^boost::static_log2] class template takes one template parameter, a value of type
+[^static_log2_argument_type]. The template only defines one member, [^value], which gives the
+truncated, base-two logarithm of the template argument.
+
+Since the logarithm of zero, for any base, is undefined, there is a specialization of [^static_log2]
+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.
+
+Note:
+
+* [^static_log2_argument_type] is an ['unsigned integer type] (C++ standard, 3.9.1p3).
+* [^static_log2_result_type] is an ['integer type] (C++ standard, 3.9.1p7).

+
+[endsect]
+
+[section Rationale]
+
+The base-two (binary) logarithm, abbreviated lb, 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 available statically (['i.e.] at compile-time).

+The original version of the Boost binary logarithm class template was
+written by [@https://www.boost.org/people/daryle_walker.html Daryle Walker] and then

+[section:mod_inverse Modular Multiplicative Inverse]
+
+[section Introduction]
+
+The modular multiplicative inverse of a number /a/ is that number /x/ which satisfies /ax/ = 1 mod /p/.
+A fast algorithm for computing modular multiplicative inverses based on the extended Euclidean algorithm exists and is provided by Boost.
+
+[endsect]
+
+[section Synopsis]
+
+    #include <boost/integer/mod_inverse.hpp>
+
+    namespace boost { namespace integer {
+
+    template<class Z>
+    Z mod_inverse(Z a, Z m);
+
+    }}
+
+[endsect]
+
+[section Usage]
+
+    int x = mod_inverse(2, 5);
+    // prints x = 3:
+    std::cout << "x = " << x << "\n";
+
+    int y = mod_inverse(2, 4);
+    if (y == 0)
+    {
+        std::cout << "There is no inverse of 2 mod 4\n";
+    }
+
+Multiplicative modular inverses exist if and only if /a/ and /m/ are coprime.
+If /a/ and /m/ share a common factor, then `mod_inverse(a, m)` returns zero.

-<h2><a name="usage">Usage</a></h2>
-
-<p>The <code>boost::static_log2</code> class template takes one template

-only defines one member, <code>value</code>, that returns the truncated
-base-two logarithm of the template parameter.</p>
-
-<p>Since the logarithm of zero, for any base, is undefined, there is a
-specialization of <code>static_log2</code> for a template parameter
-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>
-
-<h2><a name="example">Example</a></h2>

-#include &lt;boost/integer/static_log2.hpp&gt;

-<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>

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

-<h2><a name="easy">Easiest-to-Manipulate Types</a></h2>
-
-<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>
-
-<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>
-
-<h2><a name="sized">Sized Types</a></h2>
-
-<p>The <code>int_t</code>, <code>uint_t</code>,
-<code>int_max_value_t</code>, <code>int_min_value_t</code>, and
-<code>uint_value_t</code> class templates find the most appropiate
-built-in integral type for the given template parameter.  This type is
-given by the class member <code>least</code>.  The easiest-to-manipulate
-version of that type is given by the class member <code>fast</code>. 
-The following table describes each template's criteria.</p>

-<h2><a name="demo">Demonstration Program</a></h2>
-
-<p>The program <a href="integer_test.cpp">integer_test.cpp</a> is a
-simplistic demonstration of the results from instantiating various
-examples of the sized type class templates.</p>
-
-<h2><a name="rationale">Rationale</a></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>
-
-<h2><a name="alternative">Alternative</a></h2>

-<p>If the number of bits required is known beforehand, it may be more
-appropriate to use the types supplied in <cite><a

-<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>

-<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.

-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.
