What is "e" in the calculator on iPhone?

If you are asking about the "e" in the answer: Because the result is larger than can be displayed, like most calculators switch to scientific notation:

Calculators cannot do exponents (the superscripted number) so for decades the convention has been to use "e" for "exponent." So in your result, the "e7" is the equivalent to " times 10 to the seventh power."

If you turn your phone on its side, you can see the entire number.

turns to this with the phone is rotated 90°:

Hello Allan! Thank you so much for the tip about rotating the calc app in order to show very long numbers. I had no idea you could do that, it will really help me! Best iPhone tip I´ve read all year! It just goes to show that one never stops learning…Cheers, Ian.

I had no idea you could do that,

You are not alone. Last night I mentioned the rotation action to my very smart daughter who's used iPhones going back to about iPhone 5 and she was unaware of the calendar changing from standard to scientific when you "flip" it.

Thanks for the follow-up and the comment!

Cheers!

Hello,

Even after rotating the phone and it shows the long numbers, if I copy and paste it, say in Notes, it’s gets pasted in scientific notation. Is there a way for this to be pasted in long numbers instead? Thanks in advance!
