*This function gives the real coefficient of the complex number.

*This function gives the real coefficient of the complex number.

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

*IMREAL(z), Where z  is  the complex number is in the form of <math>x+iy</math>

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

* where <math>x</math> & <math>y</math> are the real numbers. <math>i</math> 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 <math>(x,y)</math> in the complex plane.  

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

*Here <math>x</math> is called real part and </math>y</math> is the imaginary part of <math>z</math>.

*This function shows the value of the real part of z.

*This function shows the value of the real part of <math>z</math>.

*A complex is said to be purely imaginary when x=0 and it is a real number when y=0.

*A complex is said to be purely imaginary when <math>x=0</math> and it is a real number when <math>y=0</math>.

*We can use COMPLEX function to convert   real and imaginary number in to a complex number.
