+# 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.

+
+[section Introduction]
+
+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
+programming problems.

+	     first_argument_type const &a,
+         second_argument_type const &b ) const;
+   };
+
+The boost::integer::gcd_evaluator class template defines a function object
+class to return the greatest common divisor of two integers.
+The template is parameterized by a single type, called IntegerType here.
+This type should be a numeric type that represents integers.
+The result of the function object is always nonnegative, even if either of
+the operator arguments is negative.
+
+This function object class template is used in the corresponding version of
+the GCD function template. If a numeric type wants to customize evaluations
+of its greatest common divisors, then the type should specialize on the
+gcd_evaluator class template.

+The boost::integer::lcm_evaluator class template defines a function object
+class to return the least common multiple of two integers. The template
+is parameterized by a single type, called IntegerType here. This type
+should be a numeric type that represents integers. The result of the
+function object is always nonnegative, even if either of the operator
+arguments is negative. If the least common multiple is beyond the range
+of the integer type, the results are undefined.
+
+This function object class template is used in the corresponding version
+of the LCM function template. If a numeric type wants to customize
+evaluations of its least common multiples, then the type should
+specialize on the lcm_evaluator class template.
+

+
+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.

+
+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

-<p>
-        The specifications for these types are based on the ISO/IEC 9899:1999 C Language

-        The organization of the Boost.Integer headers and classes is designed to
-        take advantage of &lt;stdint.h&gt; types from the 1999 C standard without
-        causing undefined behavior in terms of the 1998 C++ standard. The header
-        &lt;boost/cstdint.hpp&gt; makes the standard integer types safely available
-        in namespace <code class="literal">boost</code> without placing any names in namespace
-        <code class="literal">std</code>. The intension is to complement rather than compete
-        with the C++ Standard Library. Should some future C++ standard include &lt;stdint.h&gt;
-        and &lt;cstdint&gt;, then &lt;boost/cstdint.hpp&gt; 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.

-        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 (<span class="emphasis"><em>i.e.</em></span> at compile-time).

-        The original version of the Boost binary logarithm class template was written
-        by <a href="http://www.boost.org/people/daryle_walker.html" target="_top">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.

-      Boost.Integer provides integer type support, particularly helpful in generic
-      programming. It provides standard C99 integer types, such as might be found
-      in &lt;stdint.h&gt;, without requiring that header. 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 <code class="computeroutput"><span class="identifier">min</span></code> and <code class="computeroutput"><span class="identifier">max</span></code>.
-      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:cstdint Standard Integer Types]
-
-[section Overview]
-
-The header [^[@../../../../boost/cstdint.hpp <boost/cstdint.hpp>]] provides the typedef's useful 
-for writing portable code that requires certain integer widths. All typedef's are in namespace boost.
-
-The specifications for these types 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 for all platforms/compilers, because [^long long] is not [yet] included in the C++ standard.
-
-See [@../../test/cstdint_test.cpp cstdint_test.cpp] for a test program.
-
-[endsect]
-
-[section:rationale Rationale]
-
-The organization of the Boost.Integer headers and classes is designed to take advantage of <stdint.h> types from the 
-1999 C standard without causing undefined behavior in terms of the 1998 C++ standard. 
-The header <boost/cstdint.hpp> makes the standard integer types safely available in namespace [^boost] 
-without placing any names in namespace [^std]. The intension is to complement rather than compete 
-with the C++ Standard Library. Should some future C++ standard include <stdint.h> and <cstdint>, 
-then <boost/cstdint.hpp> will continue to function, but will become redundant and may be safely deprecated.
-
-Because these are boost headers, their names conform to boost header naming conventions rather than 
-C++ Standard Library header naming conventions.
-
-[endsect]
-
-[section:ce ['Caveat emptor]]
-
-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.
-
-As another implementation artifact, certain C <stdint.h> typedef names may possibly be visible 
-in the global namespace to users of <boost/cstdint.hpp>. Don't use these names, they are not part of 
-any Boost-specified interface. Use the respective names in namespace [^boost] instead.

-The typedef [^int#_t], with # replaced by the width, designates a signed integer type of exactly # bits; 
-for example [^int8_t] denotes an 8-bit signed integer type.  Similarly, the typedef [^uint#_t] designates an unsigned 
-integer type of exactly # bits.
-
-These types are optional. However, if a platform supports integer types with widths of 
-8, 16, 32, 64, or any combination thereof, then <boost/cstdint.hpp> does provide the 
-corresponding typedefs.
-
-The absence of int64_t and uint64_t is indicated by the macro `BOOST_NO_INT64_T`.
-
-[endsect] 
-
-[section Minimum-width integer types]
-
-The typedef [^int_least#_t], 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, [^int_least32_t] denotes the smallest signed integer type with a width of at least 32 bits. 
-Similarly, the typedef name [^uint_least#_t] 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.
-
-The following minimum-width integer types are provided for all platforms:
-
-* [^int_least8_t]
-* [^int_least16_t]
-* [^int_least32_t]
-* [^uint_least8_t]
-* [^uint_least16_t]
-* [^uint_least32_t]
-
-The following types are available only if, after including <boost/cstdint.hpp>, the macro BOOST_NO_INT64_T is not defined:
-
-* [^int_least64_t]
-* [^uint_least64_t]
-
-
-All other minimum-width integer types are optional.
-
-[endsect] 
-
-[section Fastest minimum-width integer types]
-
-The typedef [^int_fast#_t], with # replaced by the width, designates the fastest signed integer type 
-with a width of at least # bits. Similarly, the typedef name [^uint_fast#_t] designates the fastest 
-unsigned integer type with a width of at least # bits.
-
-There is no guarantee that these types are fastest for all purposes.  In any case, however, they satisfy  
-the signedness and width requirements.
-
-The following fastest minimum-width integer types are provided for all platforms:
-
-* [^int_fast8_t]
-* [^int_fast16_t]
-* [^int_fast32_t]
-* [^uint_fast8_t]
-* [^uint_fast16_t]
-* [^uint_fast32_t]
-
-The following types are available only if, after including <boost/cstdint.hpp>, the macro BOOST_NO_INT64_T is not defined:
-
-* [^int_fast64_t]
-* [^uint_fast64_t]
-
-All other fastest minimum-width integer types are optional.
-
-[endsect] 
-
-[section Greatest-width integer types]
-
-The typedef [^intmax_t ]designates a signed integer type capable of representing any value of any signed integer type.
-
-The typedef [^uintmax_t] designates an unsigned integer type capable of representing any value of any unsigned integer type.
-
-These types are provided for all platforms.
-
-[endsect]
-
-[section Integer Constant Macros]
-
-The following macros are always defined after inclusion of this header, these allow
-integer constants of at least the specified width to be declared:  
-INT8_C, UINT8_C, INT16_C, UINT16_C, INT32_C, UINT32_C, INTMAX_C, UINTMAX_C.
-
-The macros INT64_C and UINT64_C are also defined if the the macro BOOST_NO_INT64_T is not defined.
-
-The C99 macro __STDC_CONSTANT_MACROS is also defined as an artifact of the implementation.
-
-For example:
-
-   #include <boost/cstdint.hpp>
-   
-   // Here the constant 0x1FFFFFFFF has the correct suffix applied:
-   static const boost::uint64_t c = INT64_C(0x1FFFFFFFF);

+[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.
