What do values represent?

Generally, for values relative to price or cost, 1 unit is equal to 1 cent.

For example, this tasty toasted sourdough:

"items": [
    {
        "name": "Toasted Sourdough Bread & Eggs",
        "description": "Just ye old classic",
        "unitPrice": "1100",
        "totalBeforeSurcounts": "1100",
        "totalAfterSurcounts": "1100",
        "posId": "toasted_eggs",
        "quantity": "1",
        "surcounts": [],
        "options": []
    }
]</

unitPrice, totalBeforeSurcounts and totalAfterSurcountsare listed as 1100. In a more readable way, that would equate to $11.00.

Another example would be in regards to loyalty. While generally the controlling interest can implement this any way they like, Doshii have designed this field to represent a value in cents. Therefore, if you had a member with 300 points, that would equate to a $3.00 discount.
