    I don’t quite understand yours, why does it need parentheses? And requires the decimal point?

    how about [0-9]+\.?[0-9]*

        Your regex matches (for example) ‘5.’ as a number

        Yeah that’s on purpose. That’s often used in sciences to mark significant digits.

        The thing I’m confused by in yours is you’re escaping the parenthesis, so there need to be literal parenthesis in the matching number, or that’s what it showed in the regex checker.
