HP35s bug ? - Philippe - 04-04-2016 10:11 PM
Hello,
Could you confirm the following bug :
Tape this (stupid) program :
PRGM TOP
0001 1
0002 2
0003 3
0004 4
0005 RTN
Now, if you exit PRGM and push the value 10 (for instance) in the stack, you will get 10.0000000007
If the program is :
PRGM TOP
0001 1
0002 2
0003 3
0004 4
0005 5
0006 RTN
Now, you can't even enter 10 (you will get 1?)
Did i miss something ?
Thank you,
Philippe

No. I get 10.00000000. In both cases.

Philippe,
was your program memory and stack empty when entering this program? Would you mind listing the exact series of keystrokes needed to reproduce the bug?
Best regards,
Thomas
RE: HP35s bug ? - Philippe - 04-05-2016 09:49 PM
Hi,
Thanks to Voldemar for trying.
@thomas :
i reproduce this behaviour each time.
1) I clear all (Blue arrow CLEAR 3 Yes Enter)
2) then i type the program :
blue arrow PRGM
1 ENTER
2 ENTER
3 ENTER
4 ENTER
yellow arrow RTN
C
3) back to the stack, i type
10 ENTER
Then the stack show
10.00000007
10.00000007
If i edit the program and remove the line containing "4", then all works
Now, if :
1) I clear all (Blue arrow CLEAR 3 Yes Enter)
2) blue arrow PRGM
1 ENTER
2 ENTER
3 ENTER
4 ENTER
5 ENTER
yellow arrow RTN
C
3) back to the stack, i type
10
I get :
1?
If i type the ENTER key, i have a syntax error
More info :
a) if i type
1. (digit "1" + a dot ".")
I get :
1n ("1n")
Thanks for your help,
Philipe

That maybe explains deviating results: I cannot clear all as I have some programs, equations and data I want to keep.
You may already know the 35s bug list. Not sure if it is still maintained, I seem to remember there was another bug connected to the stack found a couple of months ago, but it isn't listed here.
Best regards,
Thomas

Nope, all is working fine on my two different HP-35S machines when typing your two examples.
I get 10.000 all the time, and if I do a Show, it will display the full number with all trailing zeros.
Definitely is not a bug.
You have a faulty machine.

I do maintain the bug list even though I don't have a 35S any more.
I skim a lot of postings here and can easily miss things.

RE: HP35s bug ? - Philippe - 04-07-2016 06:23 AM
Well, thanks all for your help
As Jebem said, i'm pretty sure that I have a faulty machine (@Thomas, the "clear all" command is in fact not necessary. I used it just to clearly show the problem)
Thus,I will not report this behavior as a bug in Paul's list
If someone wants to see a video of the problem, I can post it (in my Dropbox ?)
Thanks to all

I would like to see it.

I will appreciate some feedback !

RE: HP35s bug ? - Marcio - 04-07-2016 10:48 AM
Nasty!
If it's under warranty, you should ask for a replacement. This machine seems to be faulty and cannot and should not be trusted.

That's very interesting behavior, but again, my two machines, made in different years, do NOT have this behavior.
One if from 2007 week 28 (S/N CNA 72800051)
The other is from 2012 week 12 (S/N CNA21200BH)
Anyhow, HP would never release a machine with such a obvious misbehavior.
The so called 35S bugs took years to be found.
If this one was a bug, I'm sure it would be found in the very first day of testing!
What is the S/N of yours?

Most were discovered and reported fairly soon after release. A relatively few more were discovered over the years since and I'm sure more still are lurking.

Sorry, Paul, my mistake. I'm not a native English speaker, so you have to excuse me.
I meant that some bugs took years to be found.
RE: HP35s bug ? - Philippe - 04-07-2016 09:42 PM
Hi,
@Marcio, yes it is under warranty and I will ask asap for a replacement.
@Jebem, the S/N is CNA54614CH (means ?)
Thanks again
!

Philippe, have you tried a "Reset" using the hole on the bottom?

John
RE: HP35s bug ? - Philippe - 04-08-2016 12:37 AM
Very good idea !
Unfortunately, this has no effect... (Turn off the calculator without resetting anything)
I also removed the batteries, this time it produces a "memory clear", nothing more...
Definitely a faulty machine.
Thanks,
Philippe
