[Regex for positive float numbers](https://stackoverflow.com/questions/6029674/regex-for-positive-float-numbers) provides almost the correct expressions, but all of them include `0.0` and `0`. Closest desired expression is: `^(?:[1-9]\d*|0)?(?:\.\d+)?$` but this includes `0.0` and `0`.

What is the regex expression for positive floating numbers such as:

```
1.0
1.1
0.1
11

```

but do not include floating numbers such as:

```
0.0
-0.0
0
-1.0
-1.1
-0.1
-11

```
