Hi, I'm a civil engineer finishing up my Masters with a structural concentration. Ever since I finished undergrad school I started looking for a new calculator. I decided that my frustration of scientific calculator screens would come to an end. I purchased the Casio fx-CG10. Recently I was given the HP Prime as well. Before I ask my question I want to say that primarily I use these calculators simply because of the color screen. It really helps my eyes all day as my scientific calculator (Casio fx 115 ES) does not. That may not be a good enough reason for many to buy one of these color screen calculators, but I took the risk when I purchased the CG10 and I haven't looked back. My question is this, when I get a result that I want to convert to engineering or scientific format where is the ENG button? I guess I never noticed it on my Casio CG10 because of the much bigger fonts but with the HP Prime I was hoping It would be as simple as pressing a button like my 115ES Casio. Anyways, I hope you all don't mind the simple question. I don't use graphing calculators for more than what a scientific calculator can do for me, but the HP Prime, in size and screen, is unbeatable to IMO.

Thanks in advance,

Hemi79
p.s. I really couldn't find anything in its manual other than changing the result format in settings which changes all input and output format.

Welcome to PF!

On page 59 of the manual it say to press F4 (Eng)

http://www.manualowl.com/m/Casio/FX-CG10/Manual/275075?page=59

I agree. Except this is in setup (settings). I am referring getting a result for example as .000018, and pressing ENG to get 18E-6 I run into the same situation with the HP Prime.

Thank you for the help.
 
On the Hp Prime: Use your blue shift key, then setup (just under symbX key). That will bring up your three modes to configure. The middle is Number format. Since it is a touch screen, touch and you will have five selections, Engineering is the last one, touch to activate. You can also select number of digits to show, I use default of 4, but you can change as well.
