It depends on which E you mean...
The capital E button stands for "Exponent";
The lowercase e button means "natural logarithm";
& the E that can show up in the display of non-scientific & non-graphing calculators means "error" (the result is higher than the highest number it can display--usually 99,999,999--or lower than the lowest number it can display--usually -99,999,999).
(In other words, all answers before this one are also correct.)

That is a short-cut way of saying 42 X 10^3 ( times 10 to the power of something). The E will shorten it to 42E3. That's the way you would type it into the calculator. It's a great shortcut, use it all the time. I think it is also a little more accurate.
I have no idea who invented it or where it came from but that is it's usage.

I have no idea who invented it or where it came from, but from what I know E on the calculator is for natural logarithm.

The "E" on a calculator usually appears if a number is greater than what the calculator's memory can hold. For example, if your calculator can only handle 8 digits, and you entered 10,000,000 x 10,000,000, you would get the calculator to write "E" which means error.

it is the key for scientific notation. Instead of entering 50000000 you enter 5 E 7.
