The number range is designed to allow for a (2,2,5) triplet. Which fits within a 32 bit value. * The `major` number can be in the [0,99] range. * The `minor` number can be in the [0,99] range. * The `patch` number can be in the [0,99999] range. * Values can be specified in any base. As the defined value is an constant expression. * Value can be directly used in both preprocessor and compiler expressions for comparison to other similarly defined values. * The implementation enforces the individual ranges for the major, minor, and patch numbers. And values over the ranges are truncated (modulo). */ // end::reference[] #define BOOST_VERSION_NUMBER(major,minor,patch) \ ( (((major)%100)*10000000) + (((minor)%100)*100000) + ((patch)%100000) ) #define BOOST_VERSION_NUMBER_MAX \ BOOST_VERSION_NUMBER(99,99,99999) #define BOOST_VERSION_NUMBER_ZERO \ BOOST_VERSION_NUMBER(0,0,0) #define BOOST_VERSION_NUMBER_MIN \ BOOST_VERSION_NUMBER(0,0,1) #define BOOST_VERSION_NUMBER_AVAILABLE \ BOOST_VERSION_NUMBER_MIN #define BOOST_VERSION_NUMBER_NOT_AVAILABLE \ BOOST_VERSION_NUMBER_ZERO /* tag::reference[] [source] ---- BOOST_VERSION_NUMBER_MAJOR(N), BOOST_VERSION_NUMBER_MINOR(N), BOOST_VERSION_NUMBER_PATCH(N) ---- The macros extract the major, minor, and patch portion from a well formed version number resulting in a preprocessor expression in the range of [0,99] or [0,99999] for the major and minor, or patch numbers respectively. */ // end::reference[] #define BOOST_VERSION_NUMBER_MAJOR(N) \ ( ((N)/10000000)%100 ) #define BOOST_VERSION_NUMBER_MINOR(N) \ ( ((N)/100000)%100 ) #define BOOST_VERSION_NUMBER_PATCH(N) \ ( (N)%100000 ) #endif
