So... You're saying, for example, that 2.55 is actually 49 places higher than 2.5?
Wrong.
2.10 is lower than 2.8
Your logic is off.
NO - I'm saying exactly that. You are thinking with arithmetic, not logic. 55 is 49 places higher than 5, is it not? What is so illogical about that? With software versions, the decimal only indicates what type of update and has nothing to with arithmetic.
Think of it this way - the 2 indicates the major release version. The number after the decimal number just indicates the minor release update version. so:
2.8 is Build 2, version 8.
2.10 is Build 2, version ten. and so forth.
2.55 would be Build 2, version 55. Hopefully, by then we will be on 3.0, but who knows...
(By the way, my example is actually slightly off, because 2.0 is version 1, so technically, 2.8 would be version 9. Also note, my use of the terms build and version are just for illustrative purposes - I have no idea what Ford actually calls each release)
