Rational and Irrational Number calculation is made easier with this online algebra calculator. A number can be determined as rational or irrational based upon the two operations which are fraction (/) and the square root (√).

Rational Number:
It is a number that can be expressed as the quotient or fraction of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number. The set of all such numbers are referred to as 'the rationals', which is denoted as 'Q'. The decimal expansion of a rational number always either terminates after a finite number of digits or begins to repeat the same finite sequence of digits over and over.

Irrational Number:
A real number that is not rational is called irrational. Irrational numbers include √2, π, e, and θ. The decimal expansion of an irrational number continues without repeating. A set of real numbers is uncountable. Hence, almost all real numbers are irrational.

Make use of this online rational or irrational number calculator to ensure the rationality and find its value.
