=== Generic formula === | |||
Any generic quantity formula should reference the product(-name), the container and a volume or weight measure. The productname and container should (?) reference the corresponding fields. | |||
The top level quantity formula, i.e. the package a customer buys is: | |||
<big>container_unit x package_name x product_name x quantity_value x quantity_unit</big> | |||
For example: | |||
* 1 bottle of red wine comprising 70 cl (on the bottle indicated as "70 cl") | |||
=== Practical usage === | |||
* to indicate times, either a "*" or a "x" can be used; | * to indicate times, either a "*" or a "x" can be used; | ||
