Is there a quick toggle to switch views of a number back and forth between standard and
scientific notation?

I know about selecting the "mode" screen and switching through Std, Fix, Sci, and Eng (and
setting the decimal places), but this takes way more time since you'd have to go to this page,
switch, look, and then go back to switch back.

I've also found PRG-NXT-Modes-FMT, which brings up soft menu (boxes) that look like they
would do what I would want, but I have to give them a number of decimal places before the
switch because they pull the top number from the stack.

Thanks!

I have found nothing works faster than just hitting the desired
number, then hold ALPHA S C I or F I X or E N G or just S T D for no fix.

The commands I wrote about before are those. Give it a number and
then type it out. It is quick.

I should point out that you can make a custom menu, or make some key
assignments, but that is generally still not as fast as just typing it
out. Going slow it shouldn't take you more than a second or two to
switch once you've done it a few times.

Hey TW thanks for the reply.

All of the solutions so far - both yours and mine take more time and effort than I'm willing to exert. I want something that can save me from having to count zeros to write out my
answers on my chemistry exams. :P These solutions would take longer than counting the
places.

I'm thinking that maybe I'm approaching this from the wrong angle. Even when the Hp is in
STD mode the larger numbers show up with SCI notation. Is there a setting that tells it to
always show SCI in STD mode at x number of places past the decimal?

Thanks so much!

I like to do all my calculations in STD notation, then convert to SCI
or ENG after I have a final answer. The easiest way I've found to
quickly switch back and forth is to define a couple functions and
store them in the directory I'm working in (ie CHEM where I'd do all
my chemistry homework and tests).

Starting with the switch back to STD notation, I type << STD >> onto
the first level of the stack, then type std, then hit STO. That saves
it as a function mapped to one of the 6 top row buttons.

I usually use the same number of significant figures, so I have a
function with that number hard-coded. To switch to SCI with 3 sig
figs, I type << 3 SCI >>, hit enter, type a name like sci3 and hit STO.

Now I've got 2 buttons ("sci3" and "std") to quickly toggle back and
forth without having to go through the MODE menu or type the commands
every time.

If you want to be able to choose the number of sig figs when you
switch to SCI notation, you'd type << SCI >>, hit enter, type sci, and
hit STO. Then you type the number of sig figs and press your new
"sci" button.

The disadvantage to this method is that it only works in the current
working directory. I'm guessing it's possible to make it a more
"portable" solution by using the CUSTOM menu, but I haven't played
with that yet.

Hey Michael,

Thanks for such a great post. Looks like it is time for me to learn how
to make working directories. :)

Do you have any more chemistry related schemes? I'm the only one
that I know of at my school with an HP in a sea of Ti's so I don't get
to swap tricks - but I do get to show off. :P
