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).
