For the record ... in Canada .. labelling regulations require that when the amount of a nutrient (protein, fat and/or carbohydrate) is under 10 grams, it must be declared to the nearest 0.1g, or 1/10th. Once the amount of the nutrient is OVER 10g, then they only have to declare to the nearest whole gram, and they usually round UP, ie 11.5g would show as 12.

In the USA, labels are only required to declare to the nearest whole gram for all amounts. And it is permitted that if a "normal serving" of a food has less than 1g carb, then it may be listed as zero. Big problem with cream ... where a lowcarber may have several times the amount considered a "normal serving" which is only 1 Tbsp. Or the packets of sweetener or the bulk Splenda ... they call a 'normal serving" 1 tsp ... which has 0.5g carb. The label will show zero, but it sure ain't zero if you have 1/2 cup of the stuff (12 carbs! )
