Sometimes those pesky decimal points can cause confusion on your shopping list. If you want to turn on rounding rules, watch the video above and do as follows:
1. Go to Settings and turn on "Ingredient Rounding"
2. Navigate to your Ingredients page to set rounding rules for each ingredient that allows it (not for weights or volumes!)
3. Test the quantities to make sure they are working as you'd hope and if not, consider turning off rounding rules for the shopping list (click on the highlighted text in Setings).
