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

    To put this into easier form:

    (nota digit) (1ormore digit) (literal dot) (1ormore digit)

    As far as I can see in that text, none of them end with "5.4” or "3.6” or "0.0”, so no your regex wont work

    Maybe change the middle " \d+" into “\d*” , or surround the “\d+\.” with a question mark group?

      surround the “\d+.” with a question mark group?

      If you’re expecting decimals, that’s the preferred solution:

      (?<!\d)(\d+\.)?\d+(?=\s*$)

      Otherwise you could do simply

      (?<!\d)\d+(?=\s*$)

      I added the lookahead (?=\s*$) to match digits at the end of the line only with possible trailing spaces.

      Thank you. Every time someone shows me something regarding regex, I feel like I’m getting lessons from a deity.

      You actually helped me out lots. I switched it to (?<!\d)\.*\d{1}+ thanks to your comment and it kinda did the job, so thank you.

    Not specifying the regex engine you use, first of all. Second, also describe what you mean by numbers that you want to match.

      Sorry, I have no clue.

      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.

        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?

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