(?<!\d)\d+\.\d+ should match the numbers at the end of the lines and yet it won't. What am I doing wrong?

Hi all I am also a new mod for the regex community! Let's make this place shine :)

Hello~ I'm one of the new mods for c/regex

I'll try my best to keep this community a safe place where people can find good regex101 information without having to deal with any toxic nonsense!

With all the strengths and shortcomings of Chat-GPT, I wanted to share one consistent strength I found it has when working with regex.

• You can ask it to generate regex patterns for known and custom things.
  • If you are skeptical it is correct (like me), you can ask it to break down the pattern and inspect why the decisions were made. If I don't understand some fields, I type up a quick test and make sure it covers all edge cases.
• And my personal favorite, you can paste a regex and ask it to tell you what it matches to. No more writing regex and forgetting what they are for!

I don't always have the opportunity to use regex when I work and would shy away from it because it can become illegible, but now that it is so easy I find I am slapping it everywhere and I cutting down on logic when sanitizing inputs/data. The bonus is now that I'm using it more, I am becoming less reliant on having it be generated for me.
