From Wiki

google adsense reports give a day-by-day accounting of money earned, but each day is rounded to the nearest cent. This makes it very hard to tell how much is earned without a significant roundoff error (on the order of one dime per annum).

Here are the actual numbers, calculated using the formula Page_Impressions * Page_eCPM / 1000.00:

Year Ending	Dollars
2007 Feb 28	33.74105
2008 Feb 29	54.31234
2009 Feb 28	39.85144
Total	$127.90483
