I got a response from HP:
-----
Hello,
Thank you for contacting HP Total Care.
I do not believe we are replacing calculators in this case. It was not
a formal bug brought up from HP so it does not fall under warranty
replacement at this time. Although the minor difference may be fixed
later, it is unlikely that an exchange policy will be set up. This
could change though so I would suggest checking in from time to time.
Sincerely,
Joe

I just bought a HP-35s calculator, and I have to say that I'm pretty
impressed with the quality. Granted, it isn't *quite* as good as, say,
an old HP 12c, but there is a major price difference, and I actually
prefer the slightly softer, but still clicky key response of the 35s.
Anyway, I read online that there's a bug with the cosine function, where
values close to 90 degrees are incorrect:
COS 89.9999999:
HP 35s: 1.745320000E-9
Windows Calculator: 1.7453292519943295760375946128047e-9
HP 49g+: 1.74532925199E-9
As you can see, the result from the HP-35s is incorrect. I knew about
this when I got the calculator; I was rather disappointed about it.
However, the overall awesomeness of the retro-HP-ness somewhat makes up
for it.
I have a few questions about this:
1. Has it been fixed? Having a math bug in a calculator is a pretty big deal.
2. If it has, is it possible to exchange my HP 35s for a new one?
3. If it hasn't, but HP does release a later revision with it fixed, can
I exchange it? Will the warranty cover it? I'm not sure if it's a
defect in workmanship; it *is* a calculator, and it can't perform (a
very small portion) of the math it was designed to do properly...
Thanks.

Not particularly helpful. I doubt it would cost them that much to fix... and news of the fact that HP calculators can't do cosines properly can't be helping business :-)

Hello all..
This is my first time posting here. I just got an HP 35s. My first HP was a 49g+ (the keyboard sucks), and I've only occasionally played with 12cs, so I don't really know too much about how amazingly well built the older calculators were.
Anyway, the 35s is, as far as I can tell, awesome. Yes, it does have the cosine bug. I do have a question about that...
I bought the calculator knowing about it; I want to email HP asking them if they've fixed it (and suggesting that they really should), and asking if I'll be able to exchange my calculator for a new one if they do. However, I can't email them about the 35s -- it isn't on the list of products for email support (nor is the 33s, oddly enough). Any ideas? And would anyone happen to know what HP would let me do if they came out with a new revision? Or if they would even bother doing a new revision these days?
Thanks,
-- J.P.
