|---|
| 19 | Defines standard version numbers, with these properties: |
|---|
| 20 | |
|---|
| 21 | * Decimal base whole numbers in the range [0,1000000000). |
|---|
| 22 | The number range is designed to allow for a (2,2,5) triplet. |
|---|
| 23 | Which fits within a 32 bit value. |
|---|
| 24 | * The `major` number can be in the [0,99] range. |
|---|
| 25 | * The `minor` number can be in the [0,99] range. |
|---|
| 26 | * The `patch` number can be in the [0,99999] range. |
|---|
| 27 | * Values can be specified in any base. As the defined value |
|---|
| 28 | is an constant expression. |
|---|
| 29 | * Value can be directly used in both preprocessor and compiler |
|---|
| 30 | expressions for comparison to other similarly defined values. |
|---|
| 31 | * The implementation enforces the individual ranges for the |
|---|
| 32 | major, minor, and patch numbers. And values over the ranges |
|---|
| 33 | are truncated (modulo). |
