Irrational Numbers. Irrational Numbers, class of numbers that cannot be produced by dividing any integer by another integer. Integers comprise the positive whole numbers, negative whole numbers, and zero: ...-3, -2, -1, 0, 1, 2, 3.... Examples of irrational numbers include the square root of two (Ã , 1.41421356...), pi (p, 3.14159265...), and the mathematical constant e (2.71828182...). When expressed as decimals these numbers can never be fully written out as they have an infinite number of decimal places which never fall into a repeating pattern. The irrational numbers, together with the rational numbers (numbers that can be produced by dividing one integer by another), make up the set of real numbers.
