278 is broke, and not a GA.

Emerald carries the decimals to atleast 4 places. But as I noted
earlier, you have to come up with a line item (per month) cost
to use with the quantity (12 months) to get the line item total.
The line item cost has to be a dollar value, which is currently
limited to normal currency (pennies).

Working backwards:

200 / 12 = 16.66666....

However, 16.66 * 12 = 199.92 and 16.67 (the rounding Calculation that
Emerald 285 is using) is 200.04. If you look closely at your 278
invoice, the numbers simply do *NOT* add up, and a smart customer will
see that right away.
