Here is a list of articles in the Real numbers category of the Computing portal that unifies foundations of mathematics and computations using computers.

In mathematics, the real numbers are intuitively defined as numbers that are in one-to-one correspondence with the points on an infinite line—the number line. The term "real number" is a retronym coined in response to "imaginary number". Together with the p-adic numbers, the reals are a limit set of the rational numbers.

Real numbers may be represented in a variety of ways: as binary numbers, as continued fractions, and in other interesting ways, such as rational zeta series.
