I ret What does E mean in 9.0122222900391E-5? this. I'm curious how to convert this number to normal number with digits(without the "e-5"). Is there any calculator that can solve without this the "e"?
The number i'm trying to convert 5.5271479e-74

$\begingroup$You simply have to divide $5.5271479$ by $10^{74}$, that is
$$0.\overbrace{000...000}^{\color{red}{73 \,zeros}}55271479 $$
$\endgroup$ $\begingroup$Simply, e$-74=10^{-74}$, so your number is $5.5271479.10^{-74}$
$\endgroup$ 2 $\begingroup$The "E" notation means "multiply by $10$ to this power."
So 2.34E+4 would be $2.34 \times 10^4$, or $23,400$.
Also, -1.23E-2 would be $-1.23 \times 10^{-2}$, or $-0.0123$.
This is a notation that is suited for (now) inexpensive calculators. A simple seven-light character display can handle an $E$ (meaning exponent).
