Decimal seperator not localized

[markusd112]

Description
I have set the language of my nextcloud user to german. Here you use the comma for decimal seperator, e.g. "0,5 Liter Milch" (for half a litre milk).
The cookbook app doesn't accept the comma as decimal separator and gives a warning that the amount of this ingredient cannot be calculated. If I change it to "0.5" (with a point as decimal devider) it works.

Expected behavior
Nextcloud cookbook app should accept localized decimal separators.

Actual behavior
It doesn't accept a comma as separator, but language is set to german.

Versions
