Ricardo,
Doubles are inherently imprecise because of the way they store
floating point numbers. This is useful reading:
http://en.wikipedia.org/wiki/Floating_point
BigDecimal stores numbers in a non-lossy (albeit larger) format. I
would suggest avoiding doubles if you need high precision, or just
round the result if you don't.
One fun exercise, if you have an Apple ][ handy - is to type:
print 7*7
at the BASIC prompt. The answer?
49.000000000001

Hola Kieran!
Do you mean java.math.BigDecimal?
If so, does this means that java cannot add two double numbers
without a math library?
wired!
My first guess was to blame the tranport (SOAP or XML-RPC)... but I
do not have experience with these...
How does precision have to do with my PPC?
Does someone know the differences between the precision in
Objective-C and in Java?
Any how, I will rewrite it with BigDecimals and let you know...

The Calculator.java _example_ uses double ..... why not revise it
to use BigDecimal instead?

Hola!
Playing with WOWS and Cocoa I found that even a simple sum, is
buggy...
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?
