- BOOST_VERSION_NUMBER(major,minor,patch)
- ----
- Defines standard version numbers, with these properties:
- * Decimal base whole numbers in the range [0,1000000000).
- 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).
