IMREAL(z)
- is the complex number is of the form
is the complex number is of the form 
Description
- 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".
- wherex&y are the real numbers.'i' imaginary unit ..
- The complex number 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.
.
can be identified by (x,y) in the complex plane.Examples
- IMREAL("3+4i")=3
- IMREAL("-5+6i")=-5
- IMREAL("8")=8
- IMREAL("-2i")=0
