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.
0,1,2,3,4,5,6,7,8,9
[0-9]*\.?[0-9]*edit: ok no empty strings
[0-9]+\.?[0-9]*That regex implies “” is a number
If I had a nickel for every time that happened I’d have “” nickels.
yeah but by Cantor’s diagonal argument, you still wouldn’t be listing all the real numbers
