Is there a difference between writing things as "1.0E-1" and "1.0 x 10^-1"? Are they both scientific notation?

I know that if I were to write 32000 in the second way, it would be 3.2 x 10^4, but how would it look if done the first way?

Sorry, I am dumb. I didn't think that there was a difference in the way you write it, but apparently there is.

32e3 or 3.2e4.

NeWhatever is the same as writing N x 10^Whatever , but as a shortcut when writing x10^whatever is confusing or inefficient.

First one is Engineering Notation, second one is Scientific notation.

32E3

since the powers of 10 should be in multiples of 3.

Got it, thanks. I guess I was just put off by how it was being called 'scientific notation' when it is in fact something different.

Related question, are 32e3 and 3.2e4 equally correct? Could I write 0.32e5 and on and on indefinitely?
