A rational number is one that can be written as a fraction, with whole numbers in the numerator and the denominator. For example, 1/2, 5/2, 3 = 3/1, etc.
An irrational number can't be written as such a fraction. This includes most square roots, cubic roots, and higher roots; the result of logarithms, exponential function, trigonometric functions, etc., for most inputs, and special numbers such as pi and i.
