👉 In mathematics, the term "unimaginary" is used to describe a number that cannot be represented as a ratio of two integers. This means that it has no decimal representation and can only be expressed as an irrational number in its simplest form. The concept of the "unimaginary" numbers was introduced by French mathematician Évariste Galois, who studied their properties and discovered how they could be used to develop new algebraic structures such as fields.
