rational number

In mathematics, any number that can be expressed as an exact fraction (with a denominator not equal to 0), that is, as a ÷ b where a and b are integers; or an exact decimal. For example, 2/1, 1/4, 15/4, −3/5 are all rational numbers, whereas π (which represents the constant 3.141592 ... ) is not. Numbers such as π are called irrational numbers.
