About Stock Management:
WooCommerce – does not allow you to set the “Low Stock threshold” / “Out Stock threshold” as Decimal values. Only Integers.
Therefore, or set: 0 or 1, 2, … etc.
But on the Product Settings Page -> Tab “Inventory” in the “Quantity” field will be the correct value, on the Sold Decimal Quantity amount of Products.
(Maybe someday WooCommerce will allow its Users to use Decimal Quantity in Stocks.)
