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

Not specifying the regex engine you use

Sorry, I have no clue.

Second, also describe what you mean by numbers that you want to match.

So you see in the screenshot, there's a random number at the end of some of the lines, I'm trying to match that.

BTW if you don't need to capture the number, \d$ should match what you need. If regex syntax supports \d, of course.

The number is the bit I want to capture.

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?

Sorry it took so long to get back to you, I was trying to find a type of some sort.

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! 🥺
