format_babel doesn't use comma seperator from babel locale

[lassebomh]

I am trying to use pint to convert units and format them using format_babel, but numeric formats doesn't seem to respect the given locale.

Versions:

babel = "2.12.1"
pint = "0.22"

Example:

from babel import Locale
from pint import UnitRegistry

loc = Locale('da_DK')

ureg = UnitRegistry()
Q_ = ureg.Quantity

Q_('2 * feet').to('meter').format_babel(locale=loc)

> '0.6095999999999999 meter'

In Denmark we use comma as a decimal seperator, but here it's dot seperated. Am I missing something?

Indeed, there seems to be a bug her. Will fix in the next version.

Pint only supports babel <2.8 for now https://github.com/hgrecco/pint/blob/fc1aeba21823092007adc62fae96596e15aa0127/pyproject.toml#L62C1-L62C6

If I remeber correctly pint depended on some private part of babel that broke with babel>2.8.

if anyone is interested in looking into that.
