Version from SPFile

Recently I worked on a project that involved MOSS 2007 publishing sites and the SPFile object contains a couple of properties holding version information: UIVersionLabel which is a string type and returns the version number of a page while UIVersion is an integer type that returns the version as a numeric value making it easier to compare in code. It appears as though the first nine bits of this property holds the minor version number. So to check if a file is grater then version 1.0 you can perform (UIVersion > 512) and to check if the page has also been approved and published, you may also perfrom (UIVersion % 512) == 0.
