HP-11C floating display format Message #1 Posted by Craig Skinner on 16 Feb 2005, 7:40 a.m. Hi, I have a HP-11C, and it is cuurently set with a fixed number of decimal places format. How do I unfix the display format so that it displays the number of decimal places as required? I tried FIX . which works on some other models, but not it seems on the 11C. Thanks, Craig

(Brazil) on 16 Feb 2005, 11:06 a.m., in response to message #1 by Craig Skinner Hi, Craig; when you use either [FIX], [ENG] or [SCI] in the HP10C, 11C, 15C and most of the HP calculators, you should specify how many digits you wish to be shown after keying [f][FIX], [f][ENG] or [f][SCI]. For instance, if you want a fixed 5 decimal places, press: [f][FIX] 5 It works the same for [ENG] and [SCI]. (both the HP12C and 16C have a different scheme) Hope this helps.

Re: HP-11C floating display format Message #3 Posted by Tom Sherman on 16 Feb 2005, 11:18 a.m., in response to message #1 by Craig Skinner Craig, If I understand what you are seeking, you would like the calculator to display 3/2 as 1.5, but 5/4 as 1.25, and 2/3 as 0.666666666... This is called "standard" display on the HP-48G, and "normal" display on a TI-83. As far as I know, the 11C or 15C will not do this. With [f]FIX followed by a number, you can set the number of decimal places you want to round the answer to, but this will then be used for all results until changed. Cheers, Tom

Re: HP-11C floating display format Message #5 Posted by Bram on 18 Feb 2005, 4:04 p.m., in response to message #4 by Craig Skinner You do know that pressing f clear prefix shows all digits for a while (independent on the chosen format), don't you? It's nothing like the ALL format, but it may suit your needs.

"ALL" display format Message #6 Posted by Karl Schneider on 17 Feb 2005, 12:07 a.m., in response to message #1 by Craig Skinner Craig -- As Tom said, the Voyager-series models (e.g., 11C and 15C) do not offer an "all digits only as required" display format. This is how the original HP-35 displayed numbers, and is the "Normal" display mode for TI, Casio, and other manufacturers. The "ALL" display format was provided in the Pioneer-series HP calc's (e.g., 20S, 32SII) for 1988. HP provided "FIX" and "SCI" with the HP-45, successor to the HP-35. It makes more sense for the user to limit the number of digits displayed in routine practice, so as not to clutter the viewed results with insignificant low-order digits. The automatic change of format also gives confirmation that the input number was accepted. Fewer displayed digits saved battery power on the LED-display models, too. -- KS
