You are still thinking in decimal fractions, the abbreviated version number
is TWO seperate numbers seperated by a period.
Following the above examples
Version 1, Revision 9 is written as 1.9
Version 1, Revision 25 is written as 1.25
Version 1, Revision 90 is written as 1.90
This is the method CATS suggested as been easiest to test for by
software which needs to know which version it is working with. As in,
"I need version 9 do I check for 9 or 09 or 009 .... ?" :)
Other systems are used RCS for example uses 3 numbers separated by
period 1.2.3 etc.
