- -

Rationale

-

The organization of boost integer headers and classes is designed to take -advantage of <stdint.h> types from the 1999 C standard -without resorting to 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. As always, 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. - -

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. - -

c++boost.gif (8819 bytes)Integer -Type Selection Templates

-

The <boost/integer.hpp> -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.

- -

The templates int_t<> and uint_t<> supply typedefs least -and fast.  The least type be the smallest type which holds at -least the number of bits (including sign) specified. The fast type will -be at least as large as the least type, but may possible be larger.  -There is no guarantee that the fast type will actually be faster than -other possible types.

- -

Alternative

- -

If the number of bits required is known beforehand, it may be more -appropriate to use the types supplied in <boost/cstdint.hpp>.

- -

Synopsis

- -
-
namespace boost
-{
-  //  fast integers from least integers
-  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 implementation-supplied  least;
-      typedef int_fast_t<least>::fast  fast;
-  };
-
-  //  unsigned
-  template< int Bits >   // bits required, 0-32 valid
-  struct uint_t 
-  {
-      typedef implementation-supplied  least;
-      typedef int_fast_t<least>::fast  fast;
-  };
-} // namespace boost
-
- -
-

[Templates to select type based on maximum value are under development.] -

- -

Example

- -
- 
#include <boost/integer.hpp>
-using boost::int_t;
-
-...
-int_t<24>::least my_var;
- -
-

Demonstration Program

- -

The program integer_test.cpp is a not very -smart demonstration of the results from instantiating various int_t<> -and uint_t<> examples.

- -

Rationale

- -

The rationale for the design of the templates in this header includes:

- -
    -
  • Avoid  recursion because of concern about C++'s limited guaranteed - recursion depth (17).
    • -
  • Avoid macros on general principles.
    • -
  • Try to keep the design as simple as possible.
    • -
- -

Credits

The author of the Boost integer type choosing templates is Beman -Dawes.  He thanks to Valentin Bonnard and - Kevlin Henney for sharing their designs for similar templates.

c++boost.gif (8819 bytes)Compile-Time Integral -Type Limits

- -

-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 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
-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. - - -

Header integer_traits.hpp Synopsis

namespace boost {
-  template<class T>
-  class integer_traits : public std::numeric_limits<T>
-  {
-    static const bool is_integral = false;

Description

- -Template class integer_traits is derived from -std::numeric_limits. In general, it 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: -

- - - - - -
membertypevalue
is_integralbooltrue
const_minTequivalent -to std::numeric_limits<T>::min()
const_maxTequivalent -to std::numeric_limits<T>::max()
- -

- -Note: A flag is_integral is provided, because a -user-defined integer class should specialize -std::numeric_limits<>::is_integer = true, -nonetheless compile-time constants const_min and -const_max cannot be provided for that user-defined class. - -

- -Test Program

- -

- -The program integer_traits_test.cpp -exercises the integer_traits class. - -
