Shall I blame them?
You should. float and double are both floating point primitives in
java; double offers more precision (the number of significant digits)
than float. But, as pointed out, any type of float is inherently
precise.
If you want to create a calculator object, it is a good idea to use
BigDecimal. Java was originally designed as a PDA/set top box
language, and its roots often show. Treat this as an opportunity to
demonstrate the benefits of encapsulation in an object oriented
design :-).

I'd published the Calculator.java example from WO and consume it
with WebServicesCore.framework in a very straight-forward way
(the details are in http://strausz.blogspot.com/2006/11/consuming-
calculatorjava-ws.html ); while adding 3.4 to 6.6, instead of
10.0 I did get 9.999998099999999 ... close, but not correct =:+(
To whom I shall blame?
At a guess - blame floats.
