imaginaries
Numbers involving roots
Imaginaries are imaginary numbers—numbers involving the square root of negative one, which has no solution among real numbers.
Mathematicians represent this value as *i*, and imaginaries take the form of *i* multiplied by a real number: 2i, -5i.
Despite the name suggesting fiction, imaginaries are essential in physics, engineering, and signal processing.
Combined with real numbers, they form complex numbers.
