IPhone app gives different numbers than website

I guess not a huge deal, but I noticed my number totals are different on the website than on my phone app. I figured out that the phone up uses decimal points but the website rounds up. On the website it shows I have one extra gram more gram of fat and two more grams of sugar than on the IPhone app.

To me this isn't such a big deal but it took a little while to figure out why there was a difference. Many people track their numbers so carefully so one or two extra grams of fat and sugar (amongst everything else) can make a difference.
