I had several responses like Angela's and I'm sorry, I was a bit tired.
These were just trivial accessor methods of the object being
implemented here so I wasn't bothering to be consistent. Just to make
sure, I edited the code snippet to use the two (NSDecimalNumber *)
members directly:
NSDecimalNumber *t;
t = [hours decimalNumberByMultiplyingBy:rate]; //
withBehavior:numBehavior];
NSLog(@"%@ X %@ = %@", hours, rate , t);
Which gave the same results.
As to whether this is an autorelease issue, I don't see how--hours and
rate are continuing to report their correct values, and I commented out
the withBehavior: argument specifically to rule out an autorelease
issue there.

Run through twice produces:
2003-07-22 16:43:50.888 Work Timer[8128] 1 X 100 = 0
2003-07-22 16:43:50.888 Work Timer[8128] 2 X 100 = 0
I realise this is just a cut-down version of the problem so it's
probably
not the exact code, but is it possible that rate and hours differ from
[self rate] and [self hours] used in the calculation?
