$Real Numbers$ Real Numbers

Real numbers are quantities that can be expressed as infinite decimal expansions. They are used in measurements of continuously varying quantities such as size and time. Real Numbers include all positive and negative integers, all Rational Numbers and all Irrational Numbers. Real Numbers can be characterized by the important mathematical property of Completeness. Completeness means that every set that has an upper bound has a smallest such bound, a property not possessed by the rational numbers. [RA] {EB}
