Indeed. Even with some versioning schemes where 4.2 would equal 4.20 I wouldn't see the point in changing the title from what the project itself used. And if I'm reading this[1] correctly, the versions look pretty straightforward (i.e. 4.1 < 4.10 etc.).
I would say that's like pretty much every project out there. I can't come up with an example which matches the other case off the top of my head. Does that make other ones the confusing ones?
Winamp used a decimal numbering scheme. Version 5.6 is followed by 5.601, then 5.62. There's also the obligatory v1.6 < v1.666 < v1.7 version numbering of Doom.
I think Windows 3.1 to 3.11 was another example of decimal version numbering, instead of calling it v3.1.1.
Blenders version is a bit confusing sometimes. Officially its release 2.80 but that is very often called 2.8 even from official channels [1]. I was a bit confused when then announced 2.8 which is the version after 2.79.
Well their scheme does leave some questions open: Does 3.00 need to come after 2.99 or can there be a 2.100? Or if its more like 2.8.x: Can ever be a x.x.10? (we are talking here more about the scheme that actual blender releases)
How I currently understand is its just 2 numbers and 2.8 is a simplification for meaning 2.8x.
