How to have calculator output in scientific notation?

I have not seen any user guide.    

I also wish there was one.

There are some examples in the help page but it is far from comprehensive.

This calculator has some truely amazing features but i have had to see other people (perhaps people with better imaginations)  demonstrate them before I even know they exist.  

I suppose brilliant programmers do not particularly enjoy producing user documentation.     

How to have calculator output in scientific notation?

Generally speaking, most calculators have a display of 10-12 digits.So, any number bigger than that will automatically be displayed by the caculator in scientific notation.Some of them have a "mode" key, asking you how you want the calculator to display, such as "normal", "scientific", "Fixed" to specific number of decimals, "Eng" for engineering display.....etc.

I don't see such a key on this on line calculator and it outputs very long numbers as if it doesn't use scientific notation.  I'm surprised, too.

Just click the = key again then it will give scientific notation.

HaHa, great.  Thanks!

Your welcome.

Then I would say that's a mistake in the design of the calculater & you should bring it to the attention of the people who designed that calculator, so that they can correct it. If I have a very big number such as 12345678901234567890, then if you want it displayed in scientific notation, then you start counting from the right until you get to the last digit or 1, which you don't include in your counting. If you did that you should get 19 digits. So now write that in scientific notation as follows: 1.2345678901234567890. Then we multiply this number by 10 raised to power of the number of digits you just counted, which was 19, so that we have this new number in scientific notation: 1.2345678901234567890 X 10^19. That's how scientific notation is written. Normally, you are asked to truncate the 1st. part to few digits between 2-10. Such as 1.23456 X 10^19. The last digit in the 1st. part is generally rounded off to 7, if  the number after it is 5 or bigger(which is 7 in this case), so that it becomes: 1.23457 X 10^19. And that's the end of this saga!!!!. Good luck. Hope you understand it now.

There is no mistake

If you put this number in the calculator 

12345678901234567890

and click = then it displays

1.2345678901234568e19

at the top it look like this 1.2345678901234568 x 10¹⁹

Just use your brain to truncate (that means chop off if you not know) the part you not want.

Why is that a  mistake in the design?

I think it works good.

Dragonlance:

I was simply responding to the young person who didn't know how to use the calculator. After you instructed him/her on how to use it, then I realized that he/she had made a mistake!. But I had already written my comment before you straightened him/her out. I know nothing about the calculator. I use my own HP scientific calculator. I don't use any online calculators.

I think you are both correct.  I am surprised that if you input two numbers in scientific notation which are to be multiplied, the output after you hit the = sign is not in scientific notation-- as I just learned, you must hit the = sign a second time to see scientific notation.   I can live with that, but I haven't seen it that way on the several scientific calculators I've used.  I don't understand why it works that way, but it's ok now that I understand it. BTW, are there written instructions or a user's guide of some kind for looking up things like this?

There are some help instructions but this do a lot of things that are not listed. 7UP told me that Mr. Massow probably removed them because so many use this calculator now it bogs down the servers.

Curious how you first discovered to hit = key a second time in order to see result in scientific notation?
