WP 34S Displayformat
My prefered notification is ALL 2 and ENGOVR. Up to 2 zeros can appear after the decimal mark before the display switches to engineering notation.
It works perfectly with irrationional numbers but i think it doesn't work with short rational numbers: 5 1/x > 0,2 10 / > 0,02 10 / > 0,002 10 / > 0,0002 and so on up to 10 zeros after the decimal mark. Is this a bug or a feature? Many thanks in advance, Michael

Look at the green manual, p.72: ALL displays all digits as long as they fit the display width; it will switch to SCI (or ENG) only to avoid flowing over the display limits. With your number, no flowing happens. Best regards, Pascal

RE: WP 34S Displayformat
Hi Pascal,
sorry, I am a relative new user of HPcalculators. I brought a HP50g three years ago and I'm not so happy with it. One reason is the circumstantial change of the displaymode. I am an electrical engineer and i'll never use a number like 0,002. On the HP50g I have always to switch the mode manualy. Annoying! So I was very interested in the WP 34S cause I read in the beginner guide about ALL n, ENGOVR and DISP n. When I get it right, I have to type ALL 0 on the WP34S to get the same as with ALL in the HP42S. But the ALL n (n>0) should allow n1 zeros on the right side of the radixmark. I am not sure, but thats how I interpret the manuals. kind regards Michael

If the number fits the display completely and a switch to scientific notation is not required, show it in FIX mode. 2. If the number does not fit the display AND it is less than 10^{–n}, the display switches to SCI (or ENG if ENGOVR is set). If I get you right, you want the SCI/ENG switch for ANY number that is below a certain threshold, e.g. below 0,01. So that for instance 0,00012345 is displayed as 1,2345 E–4 (or 123,45 E–6) although it would fit the display in FIX mode. I do not know how this could be accomplished. Dieter

Hi Dieter,
thanks for your explanation. Quote:2. If the number does not fit the display AND it is less than 10^{–n}, the display switches to SCI (or ENG if ENGOVR is set).I didnt get the AND. My fault. Quote:If I get you right, you want the SCI/ENG switch for ANY number that is below a certain threshold, e.g. below 0,01. So that for instance 0,00012345 is displayed as 1,2345 E–4 (or 123,45 E–6) although it would fit the display in FIX mode. I do not know how this could be accomplished. Yes, that's what I want. My TI57 did it 35 years ago and I think every Casio or Sharp do so. When my students present me a result of 0,0001234kg or somethink like 1,45 * 10^0 meter, they are kidding me. I can't believe it!

That's not the calculator's fault. #) Obviously there are some basics that you cannot expect (today). Dieter
