append an existing string with notepad++

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?

Solution
    • Ctrl+H
    • Find what: \[\d+\K(?=])
    • Replace with: .0
    • CHECK Wrap around
    • CHECK Regular expression
    • Replace all

    Explanation:

    \[      # openning squarre bracket
\d+     # 1 or more digits
\K      # forget all we have seen until this position
(?=])   # positive lookahead, make sure we have a closing squarre bracket after
