I have multiple text files opened in Notepad++. And each file is like this.

```
[11]
[205]
[77]

```

I'm searching for `[[0-9]+]\s` in regex mode, but I don't know how to replace it to the output I need.

And I want to append a string like this in all opened files, like this.

```
[11.0]
[205.0]
[77.0]

```

I'm searching for `\[[0-9]+\]\s` in regex mode, but I don't know how to replace it to the output I need.

How to do this?
