completeness principle
The completeness principle is a property of the real numbers, and is one of the foundations of real analysis. The most common formulation of this principle is that every non-empty set which is bounded from above has a supremum.
This statement can be reformulated in several ways. Each of the following statements is to the above definition of the completeness principle:
- 1.
The limit of every infinite

decimal sequence

is a real number.
- 2.
Every bounded
monotonic sequence is convergent

.
- 3.
A sequence is convergent iff it is a Cauchy Sequence
