You've apparently not learned that (1/10) cannot be precisely represented in binary floating point. It's an infinite repeating expansion, which has to be truncated at some point (heh). Multiplying that by 10 does not yield 1.0 any more.

If you want precise pennies, you must count in pennies (using integer values for pennies).
