Answer 1

This is scientific notation, and is shorthand for

$$\times 10^{16}$$

So for example, 1.77e+3$ = 1.77 \times 10^3 = 1770$.

Answer 2

Whenever you see a number like: $$p.qrstuvw \ e+x$$ (where $p.qrstuvw$ is some random decimal number), it means $$p.qrstuvw\times 10^x$$ Your number: $$2.392537302040576e+16$$ means: $$2.392537302040576\times 10^{16}$$ I see this $e$ notation a lot when using a graphing calculator app on my iPad. When I "zoom out" a lot, these kinds of numbers are labeled in the x and y axes: $$5.07412e+9$$ That just means: $$5.07412\times 10^9$$ Note: This $e$ is not Euler's number
