Irrational number

Term · Computing and IT · MLC-T-CMP-000625

A number that cannot be expressed as a simple fraction (a ratio of two integers) and has a decimal representation that neither terminates nor repeats. In computing, irrational numbers must be approximated by rational numbers, such as floating-point values, because a finite amount of memory cannot store an infinite, non-repeating sequence of digits. Examples of irrational numbers include pi (π) and the square root of 2.
