How to store values on a Scientific Calculator?

Hey,

I'm wanting to know how to store values on my scientific calc.  It is a Casio, but i'm assuming they are all pretty similar.
Whenever I do a chem question, my answer is always slightly off because I use a rounded mol value instead of the calc one which for whatever reason I've had to erase.  Obviously in exams i can't do this, so does anyone know how I could store values in my calc?

Thanks.

There should be a RCL button
Above that is STO function, which I think is used for storing numbers

I just bought a Casio, and I'm still learning how to use it :P

No problem, just out of interest, what model do you have???

ok cool
i got an fx-993 (from Japan) :P
it can do calculus :D

Lol I had no idea my scientific calculator could store values until after a year of using the TI-84 for Methods.

how tight are vcaa with rounding errors in science?
if your answer is a bit off but the number of sig figs is right, would you still get full marks, or are you expected to never round until the very end?

It's not that hard to develop a "never round until the very end" habit. Obviously it's safer so there's really no point with pursuing the former option.

+1, definitely go at least three or four decimal places/sig figs further than your answer when working, then you'll be fine

yeah I'm always going to do that, but it's just a pain especially when you've had to do a mole to mass calculation and then you need to reuse the initial mole value again to do another calculation, but I know how to store values now which will make it a lot easier.
