Yeah, my fault, but 5.45, 1.25, 99.00, 2.45 will create a that kind of
alignment which stronly suggest its .99. Of course it's not printed as
such, but visually it can trick you, that's why decimal points are
never supressed anc softwar has options to align coluns to the decimal
point.

Never desirable for me, but I never use d9, I always do d0, but you are right.

For the grouping ',' I see your point, I normally just use defaut
conversion for these as I dislike the grouping.

As I said, I could see a legitimitate case for Dd similar to the 09
stuff, but having so many replace options ( I think you can even do
<trim(trailing '.' from to_char(number, 'FM9999D99'))>, which is
easier on the eye but fails on locales, as the regexp does ( as a
note, in Spain they are inverted, dot for grouping comma for decimals
) ) I do not think it's a big deal, uglier things are coded by me
continuously nearly via muscle memory.
