yeah, but i don't think these are decimals, are they? Since when are there two levels of decimals?
What I want to say, in my understanding, PHP Version 5.5.36 is newer than 5.5.9. Because they start with 0 and then go up with the number, not down.
PHP sees this very similar to me:
5.5.38 - Released: 21 Jul 2016
5.5.9 - Released: 6 Feb 2014
I guess your comment was sarcasm.
