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

Sorry, I have no clue.

What do you use to apply your regex? Programming language, library, command line tool etc.

there’s a random number at the end of some of the lines, I’m trying to match that.

Is it decimal? One digit or multiple digits? Natural, rational?

The app offers this https://github.com/gedoor/legado/blob/master/app/src/main/assets/web/help/md/regexHelp.md Which I hope you find fruitful as an indication.

In the screenshot above, you can see it differs. I feel like I'm not doing your kindness justice with my sparse information, sorry! 🥺
