I don't know how to convert $\mathtt{7.6923077e+13}$ into pure numbers without $\mathtt{e+}$.

2e+x is short hand notation for $\times 10^{x}$, I believe. So it's just $7.6923077 \times 10^{13}$ – Troy Nov 27 '16 at 11:14

2"e+13" means "times $10^{13}$. Google "scientific notation". – David Mitra Nov 27 '16 at 11:14

1This comes from the Olden Days when computer printers could not write exponents and such things. – GEdgar Nov 27 '16 at 13:43

Move the decimal dot 13 positions to the right: \begin{align}7.6923077\text{e+}13&=7.692307700000000\!\dots\text{e+}13=76923077000000.00\!\dots\\&=76,\!923,\!077,\!000,\!000 \end{align}

$\mathtt{e+x}$ and $\mathtt{e-x}$ are often used to represent $10^x$ and $10^{-x}$. If you are familiar with Computer Science, these are used in representing numbers while using Floating type modifiers.
For your number $\mathtt{7.6923077e+13}$, I would say that it just represent $7.6923077 \cdot 10^{+13}$. I think moving the dots to right and decreasing the power is not a big deal now.
