Is negative power always signifies a fraction if a number is in normalized scientific notation

Question

Is my understanding correct that a number is in a scientific normalized form, a negative exponent always signifies a fraction? I'm thinking that if in a normalized form only one digit is allowed before the radix point, it's enough to have $-1$ in the exponent to have a fraction

Answer 1

OK, so, we're talking about numbers of the form $\pm d_0.d_1d_2\dots\times10^n$ where the $d_i$ are digits, $d_0\ne0$, and $n<0$. Well, any such number is strictly between $-1$ and 1, and is not zero, so it's certainly not an integer.
