REAL NUMBERs are defined uniquely by "infinite" (unending) sequences of natural numbers. The sequence IS the real number. LIMIT is a defined property of real numbers.

One might as well omit trailing zeros and also omit the decimal separator for integers, so that zero can be written as just 0. For uniqueness, it would also be necessary to write 2.19999..., say, as 2.2, which adds a bit of inelegance to the definition.
