IMREAL(z)

This function gives the real coefficient of the complex number.
IMREAL(z), $z$ is the complex number is in the form of $x+iy$
where $x$ & $y$ are the real numbers. $i$ imaginary unit. $i={\sqrt {-1}}$ .
The complex number $z=x+iy$ can be identified by $(x,y)$ in the complex plane.
Here $x$ is called real part and $y$ is the imaginary part of $z$ .
This function shows the value of the real part of $z$ .
A complex is said to be purely imaginary when $x=0$ and it is a real number when $y=0$ .
We can use COMPLEX function to convert real and imaginary number in to a complex number.
