What is a decimal real number?

A real number is a number that can be represented as a (possibly infinite) decimal expansion, such as 2.56, −3 (which is −3.0), 1/3 (which has the infinite decimal expansion 0.333…), and π. Every integer and every rational number is a real number, but numbers such as √2 and π are real numbers that are not rational.
