| |
| 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). |
