ENG button (like Casio calculators) on HP Prime Message #1 Posted by uklo on 27 Oct 2013, 8:12 p.m. Hello, i have always used Casio calculators now i bought the HP Prime & i have a simple question. It is possible to change the number format (only the result) to engineering with one button? I know it is possible to change the number format but it's tedious to change it entering to settings (i not always want the result in that way) Thanks

Re: ENG button (like Casio calculators) on HP Prime Message #3 Posted by uklo on 2 Nov 2013, 12:44 p.m., in response to message #2 by Michael de Estrada Hello Michael, thanks for the answer. I have done this: EXPORT eng(X) BEGIN LOCAL ans; ans:=X; HFormat:=3; RETURN ans; END; it works fine but i have two problems: 1.I want to assign it to a button, like to be at CAS mode, the touch button "simplif" to have a button "eng"... is that possible? 2. I don't want that it changes the mode which i'm working. In order to do that i've tried to put a HFormat:=0; after the RETURN but that didn't work. Thanks :) Edited: 2 Nov 2013, 1:45 p.m.

Re: ENG button (like Casio calculators) on HP Prime Message #4 Posted by LHH on 4 Nov 2013, 9:45 p.m., in response to message #3 by uklo Maybe this could be added to the time/date/battery popup. Just noticed you can change the angle setting there (degrees or radians) via touching. I switch formats often going from scientific to financial and back again. Somewhat more tedious than it probably should be. This is the original message: http://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/archv021.cgi?read=254063#254063
