Maple bugs are ubiquitous: A bug the long-liver in convert
Vladimir Bondarenko
Hello, all Maplesoft's actual and potential customers
over the world,
Our calculations reveal that you or me can trip over a
Maple bug and tumble at virtually each spot; in other
words, the diversity of Maple bugs impresses the eye.
Here comes a bug the long-liver in convert discovered
by the VM machine 2 hours ago. In human readable form
it can be represented it in such a way.
f0 := hypergeom([-1/2, 1/4, 3/4], [1/2, 3/2], 1):
f1 := convert(f0, StandardFunctions);
evalf(f0);
evalf(f1);

Hi Dave,
Do you expect me to get feeling excited or disappointed?
If you would have told me that the melting point of potassium
is about 63.65 degrees Centigrade at the normal pressure, would
you have expected from me a splash of joy, or a wild bout of
the total, utmost disappointment?
You might think, along with some other posters, that I am
looking for some response from my readers. Yes, I am happy
with a response. Also, if a reader selects to keep silence,
it's great, too. But the main goal of our posting is different
from getting of any kind of response.
VB>> Hello, all Maplesoft's actual and potential customers
VB>> over the world,
I am a Maplesoft's customer, and I am shocked with a way this
company pays to quality. In fact, it looks like, for an external
observer, that the Maplesoft's programmers run, to and fro, over
the Maple kernel and hack it with big sharp broadaxes...
And because of this, I have wasted LOTS of my precious time.
Trying to bypass the Maple bugs when possible etc... I've
contacted Maplesoft repeatedly, all in vain!
Please kindly ignore our messages. Or please kindly take them
into account. Or please kindly keep reading some of them while
ignoring the rest. Or a linear combination of the above-said...
or... There are a zillion of choices there ;)
You do not like chemistry? It would be quite funny had everyone
would like chemical facts.
I keep writing about the melting point of the potassium. The
melting point is an invariant w.r.t. my or your desire to know
or do not know about it.
It's not a religion. It's a science of quality assurance. Like
strength of materials or quantum chromodynamics.
Best of luck to you,
Vlad

Perhaps you don't understand the term 'killfile'. There's no point responding.
And welcome to mine, BTW.

Perhaps you don't understand our goals. Not all of them
have been declared publicly. All in good time.

Bye-bye, don't worry, stay happy.
'Fraid, whether you like this or not, if you use Maple for
something more serious than 2+3; you almost inevitably
visit our sites again.
By several reasons.
