Imaginary Number

a number of the form x + iy, where i = x and y are real numbers and y ≠ 0; that is, a complex number that is not real. Imaginary numbers of the form iy are called pure imaginary; sometimes only the latter are referred to as imaginary numbers. The term “imaginary number” appeared after such numbers had already entered general use although their real meaning had not been ascertained.
