Indeed, the Avogadro number is an integer that is always given in the form of a floating point number. The reals is such a useful abstraction.

No, it is typically described using scientific notation - floating point is a fixed width representation of a number with fractional parts.

And floating point numbers - and scientific notation - can both only express rationals. They aren’t ‘reals’.

My point was that it seems that in calculations it is useful to think of very large integers that are known to some approximation as real numbers.
