👉 In mathematics, a subrational number is a real or complex number that cannot be expressed as a ratio of two integers. This means that for any integer n, there exists no rational number x such that x/n = r, where 0 < r < 1 and n is an integer. For example, the square root of 2 (which is irrational) can be written in terms of its decimal expansion as √2 = 1.41421356
