Daily values #1051

Closed aleene closed 3 years ago

aleene commented 3 years ago

I started with the possibility to have the percentage of daily values shown. But I do not remember where I ended up.

Presentation: can only be shown when a portion is available. If so the fraction/percentage can be calculated and shown. But also only if we know the daily need for that nutrient. Otherise nothing must be shown.

Edit: input as percentages, store as value per portion.

The daily values can not be written to OFF, they are interpreted as gram (per serving or pe 100g).

The daily values are converted to gram per serving and then written. Thus circumventing the OFF limitation.
