Regex for matching decimals only, not integers

Question

I'm looking for a regex to match decimal numbers only, but to fail on integers.

For example, the following numbers should pass

0.00
1.00
-1.00
3.3
2.22123

But the following should fail

I don't know why this is so hard to find/create, but I'm not having any luck. All available regexes that I found online don't exclude integers.

What have you tried? What didn't work? What did you get? What did you expect? What doesn't work with your code and where is it? — Toto, Feb 19 '20 at 16:42
You closed the question and added a related to a question that specifically asks for something else (matching floating point numbers AND integers, whereas my question wants to exclude integers) — Nick Mullen, Feb 25 '20 at 17:04
