static bool
compare(string $version1, string $version2, string $operator, int|null $precision = null)
Compares two ICU versions with an operator. This method is identical to {@link version_compare()}, except that you can pass the number of regarded version components in the last argument $precision. Also, a single digit release version and a single digit major version are contracted to a two digit release version. If no major version is given, it is substituted by zero
