*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.  

*IMREAL(z), Where z  is  the complex number is in the form of "x+iy".  

*x&y are the real numbers.'i' imaginary unit .<math>i=sqrt(-1)</math>.  

* wherex&y are the real numbers.'i' imaginary unit .<math>i=sqrt(-1)</math>.  

*The complex number <math>z= x+iy</math> can be identified by (x,y) in the complex plane.  

*The complex number <math>z= x+iy</math> can be identified by (x,y) in the complex plane.  

*Here x is called real part and y is the imaginary part of z.

*Here x is called real part and y is the imaginary part of z.
