When you use Microsofts calculator's Exp function it does not raise the number you enter exponenently it requestions another number and then does this

result = firstnumber * 10^second number

What is it doing?

Well if you want to calculate for instance $$2^5$$ you should use the $$x^y$$ function not the Exp function, the Exp function calculates $$2 \cdot 10^5$$.

I hope that I understood what you meant.

Well this E stands for $$\cdot 10^{2nd nr.}$$, for example, 2E5 is the same as $$2 \cdot 10^5$$. So it is for multiply the first number with 10 to the power of the second number(after the E).
