Rosala it was good that you thought of that other thread.

This is very confusing and in my opinion is is very bad notation but

If I enter   10000e^-2.835 into the web2.0calc this is what I get.

$${\mathtt{10\,000}}{\mathtt{\,\times\,}}{{\mathtt{e}}}^{-{\mathtt{2.835}}} = {\mathtt{587.185\: \!258\: \!338\: \!722\: \!9}}$$

But if i enter this  10000e-2.835     Without the ^ lets see what happens.

Nothing - NO on this site calc I cannot bring it up as anything other than what it is here.

On many calculators you use the EXP button to bring up 10 to the power of.

And according to the other mathematician some calculators drop the XP and just use E to mean 10^

It is very confusing.

Ater looking at this again, I don't know what buttons I pushed on the calculator, but it's definitely NOT some decimal between  0 and 1 !!!

(I can't believe I didn't catch such a blatant error!!)

I'm even taking a pair of my sunglasses away as a self-imposed punishment....!!!

Here they are.  A gift from me.

A number like 9.0e9 may be interpreted as 9.0*109 only when the value following the "e" is an integer (positive or negative) and there is no exponentiation symbol ("^") between it and the "e".  In the question here, these conditions don't hold so we have to interpret this as:

$${\mathtt{10\,000}}{\mathtt{\,\times\,}}{{\mathtt{e}}}^{-{\mathtt{2.835}}} = {\mathtt{587.185\: \!258\: \!338\: \!722\: \!9}}$$

That is true Alan but what I was experimenting with is how this web2.0calc would interpret

10000e-2.835

So I plugged it in and this is what I got.  So the web2 calc does not interpret it this way.

$$\mathrm{ERROR}$$
