Products with 1/2 and 1/4 is added as 2 and 4

[odin-h]

What

Stuff like one half and one 4th L/KG is not converted correctly. Only the last digit after the slash is kept.
Here are two examples of 0,5L cartons of chocolate milk with the quantity written as 1/2L https://prices.openfoodfacts.org/app/products/7038010002625
https://prices.openfoodfacts.org/app/products/7038010066191

Steps to reproduce the behavior:

1. Add a product with 1/2 unit of measurement

Expected behavior

Would be that fractions got converted to floats.

Hi @odin-h , this is a more of a problem on the openfoodfacts-server side.
Open Prices syncs with the OFF databases every day, and we store a subset of each product field.

Indeed, for 7038010002625 the data is incorrect : https://world.openfoodfacts.org/api/v2/product/7038010002625.json

"product_quantity": "2000",
"quantity": "1/2 L",

This was the issue - openfoodfacts/open-prices#115 - where we introduced product quantity, there's a link to the implementation in the openfoodfacts-server, maybe let them know there ? and/or on Slack ?

the quick fix is to edit the product quantity field directly in OFF, it doesn't seem to parse correctly the 1/X, better to change to 0,5 or 0,25 👍
