Function
Queries the version number based on a software package name. The version number is a numeric value. It is calculated using the weight of the major, minor, and patch versions in the version field of the version.info file in the package installation directory.
Numeric version numbers are obtained for comparison. A larger number indicates a later release. You can use the numbers to learn the release sequence of versions and distinguish the calling logic of different APIs based on the versions in code.
Currently, the released versions include alpha (internal test version), beta (public test version), release candidate (RC), and release. For the same base version, the version numbers increase in the following sequence: alpha < beta < RC < release. For example, 9.0.0-alpha.1 < 9.0.0-alpha.2 < 9.0.0-beta.1 < 9.0.0-beta.2 < 9.0.0-rc.1 < 9.0.0-rc.2 < 9.0.0 < 9.0.1.
