Code to add this calci to your website  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.
