There are two types of versioning settings available in sharepoint library. Major and minor versions. But minor versions will show the versions as 1.1,1.2 ,1.3 ........to 1.9 .then it will move to 2.0 Is it possible to make the version in a pattern of 1.01,1.02,1.03.....1.99 ?
What you are suggesting isnt possible in SharePoint, and probably hard to implement too. In SharePoint 2010 you can create custom document id's where you can control prefixes http://www.zimmergren.net/archive/2010/04/13/sp-2010-sharepoint-server-2010-creating-your-custom-document-id-provider.aspx
