18 | Defines standard version numbers, with these properties: |
19 | |
20 | * Decimal base whole numbers in the range \[0,1000000000). |
21 | The number range is designed to allow for a (2,2,5) triplet. |
22 | Which fits within a 32 bit value. |
23 | * The `major` number can be in the \[0,99\] range. |
24 | * The `minor` number can be in the \[0,99\] range. |
25 | * The `patch` number can be in the \[0,99999\] range. |
26 | * Values can be specified in any base. As the defined value |
27 | is an constant expression. |
28 | * Value can be directly used in both preprocessor and compiler |
29 | expressions for comparison to other similarly defined values. |
30 | * The implementation enforces the individual ranges for the |
31 | major, minor, and patch numbers. And values over the ranges |
32 | are truncated (modulo). |
