Description

This function gives the real coefficient of the complex number.
MREAL(z), Where z is the complex number is in the form of "x+iy".i.e.
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.
