Note that due to TIntegerHelper you can write:

Yes, but sometimes we want to write like:
glVertex3f(-1.0, 1.0, 1.0);
glVertex3f(-1.0, 1.0,-1.0);
glVertex3f(-1.0,-1.0, 1.0);

Did I understand this correct: It should not complete (invoke the selected item) when pressing a comma. It should simply close.

A little different, but maybe it's OK, so that I will not press 'esc' all the time.

And I think when press the "backspace" key it should be closed too.

The backspace is needed to edit a mistake in the selection.

Btw, I personally have disabled the automatic completion box after '.', so I didn't notice this bug yet.

"The backspace is needed to edit a mistake in the selection."
I mean in this case: after the '.' there is no characters.

And for the issue I tried to add some code at CheckStartIdentCompletion function and there may be many problems because I'm not familiar with Lazarus source code.
    for p:=LogCaret.X-2 downto 1 do
      if Line[p] in ['0'..'9'] then
        if Line[p-1] in ['a'..'z','A'..'Z','_'] then
        else if (Line[p-1] in [' ','=','(','[','+','-','*','/']) or (p=1) then
Do not laugh my code. hahaha­čśä

Maybe this problem is more complicated

IDE should show autocompletion after '.' only if it's not in float-number context.

Until a final solution is found...

You should be able to avert the problem to 99% if you go to Tools > Options > Codetools > identifier completion

Disable "include identifiers containing the prefix". Then only idents starting with the text you typed will be found.
The completion box will still show, but after the dot you will type at least one digit. And then no identifier starts with a digit. So no completion is possible as soon as you type the first digit after the dot.

You can also look for the drop down called "include words" and set it to "dont include". But that still leaves a very few completion for some digits....

Thanks, I set "include words" drop down to "don't include" and the completion box does not show.

@CudaText man: There is no concept of "float-number context". Due to type helpers "2.Identifier" can be valid as well.
