Am I misunderstanding the docs? Or am I doing it wrong?
So I'm following the documentaton here regarding the formatting of numbers which suggests that using stackfltfmt:"~,2f"; should result in {@float(2/3)@} producing 0.67 but it doesn't, I get 0.66 both in the CasChat and in a question. Similar behaviour for other fractions 7/9 => 0.77 for example.

You need to read the Maxima documentatoin carefully. I think 'float' is truncating the number, not rounding it. If you want to round the number, you need to use the round function. Only, Maxima users 'Banker's rounding', which is probalby not what you want.
See https://docs.stack-assessment.org/en/CAS/Numbers/#notes-about-numerical-rounding for wht you do want.

I was fiddling around with different maxima functions a few month ago and arrived at the conclusion, that
significantfigures(number, number of digits)
does ordinary "5 always up" rounding. See also our (a little lengthy) discussion here:
