IMAGINARY(ComplexNumber)

is of the form .
- IMAGINARY(), returns the imaginary coefficient of a complex number

Description

This function gives the imaginary coefficient of a complex number.
Complex number is a combination of real and an imaginary number.
Imaginary number is a real number which is multiplied with the imaginary unit $i$ , where $i={\sqrt {-1}}$ .
When imaginary number $bi$ is get adding to the real number $a$ , then it forms a complex number.
Also when we are squaring the imaginary number $bi$ , it will give the negative real number ${-b}^{2}$ .
For eg $(5i)^{2}=-25$ .
We can use COMPLEX function to convert the real and imaginary coefficients to a complex number.
A complex number is a imaginary number when the real part is zero.
