Definition: In mathematics, "imperfectious" is a mathematical concept used to describe a number that has an infinite decimal representation. It refers to a number whose digits repeat in such a way that when one divides it by any integer other than 1, the result is always non-zero.
For example, consider the decimal representation of the number 2.8571428571... The digit 8 repeats infinitely, and this pattern continues indefinitely. Therefore, we can say that
