None, decimals aren't numbers, but an abstraction of numbers.

None. You're interpretation of reality is abstract to reality.

Any segment of the real line can be bijected with the entirety of the reals.
Let $f:(0,1) \rightarrow \mathbf{R}$ with $f(x) = \frac{2x - 1}{x - x^2}$ then f is a bijection between (0,1) and the reals (annoyinf proof left to the reader as exercise)
Now if you consider $T:(0,1) \rightarrow (a,b)$ with $T(x) = a + (b - a)x$ then the function $g:(a,b) \rightarrow \mathbf{R}$ with $g(x) = f(T^{-1}(x))$ is a bijection between any segment (a,b) and the reals.
You should also proof this as an exercise
