HP 33s Updated Manual Message #1 Posted by Chuck Westen on 20 Oct 2004, 1:53 p.m. I don't know if anyone has already discussed this but HP has issued a manual update, dated 9/2/2004, at HP.com. I appears that HP acknowledges the problems identified in this forum with the HMS & retangular to polar conversions and the combination function. The maunual update gives "workarounds" for these problems.

Re: HP 33s Updated Manual Message #2 Posted by bill platt on 20 Oct 2004, 4:26 p.m., in response to message #1 by Chuck Westen Hi Chuck, Thanks for the tip. I had noticed that they had gone to edition 2 of the manual, fixing the errata on page 13-9.

Re: HP 33s Updated Manual Message #3 Posted by Norris on 20 Oct 2004, 4:27 p.m., in response to message #1 by Chuck Westen As previously discussed on this forum, the 33S can be programmed with "replacement" functions that automatically incorporate the same workarounds suggested by HP. Examples: Replacement polar conversion function (XEQ T): LBL T x=0? ABS x<>y x=0? ABS x<>y y,x->theta,r RTN Replacement HMS conversion function (XEQ U): LBL U CF 4 x<0? SF 4 FS? 4 +/- ->HMS FS? 4 +/- CF 4 RTN

HP-33S bug list. Message #4 Posted by Michel on 20 Oct 2004, 4:36 p.m., in response to message #3 by Norris I just receive my HP-33S and don't notice @bug@ with polar conversion. Can someone tell me where to read all the bugs that the HP-33S had or still have (for now...). Thank you Michel

Re: HP-33S bug list. Message #5 Posted by bill platt on 20 Oct 2004, 5:20 p.m., in response to message #4 by Michel search for bug list 33s (slelct "all") in a search of archive 14

Re: HP-33S bug list. Message #6 Posted by Norris on 20 Oct 2004, 5:38 p.m., in response to message #4 by Michel The recent 33S User's Manual Update, which is currently posted at http://h10032.www1.hp.com/ctg/Manual/c00251639.pdf describes the most serious bugs identified to date, and includes examples. The polar conversion bug can affect (x,y) values where x or y equals 0. Try this for entertainment: 3 ENTER 0 ->polar ->rect ->polar ->rect

Re: HP-33S bug list. Message #7 Posted by Michel on 21 Oct 2004, 8:51 p.m., in response to message #6 by Norris Wow, on the HP update manual it is said to produce error only with -0 (if i understand the update...). With your simple example, it shows that it is always the case with a "normal" zero... I think it's the worst but i encounter with the calculator.

Re: HP 33s Updated Manual, but not updated calc. Message #9 Posted by Tom (UK) on 21 Oct 2004, 3:38 a.m., in response to message #1 by Chuck Westen As HP have issued 'work arounds' does that mean they are NOT going to fix the calculator? If that is so HP will go down another notch in my estimation. These bugs should be fixed, I can't think of another calculator maker with bugs that affect simple 'every day' calculations.

Re: HP 33s Updated Manual, but not updated calc. Message #10 Posted by John on 21 Oct 2004, 7:37 a.m., in response to message #9 by Tom (UK) My guess is that it may be much quicker to fix a PDF to include fixes for these bugs than to get them taken out of the rom by a fix. I would guess a fix is coming, but that HP wants to give their customers a work-around until that time. Why is it that HP is always thought of as Mr. Evil around here?

Re: HP as Mr. Evil? Message #11 Posted by Mike (Stgt) on 21 Oct 2004, 8:14 a.m., in response to message #10 by John Because you have always enough faultfinder in the past tense. Ciao.....Mike
