IMREAL (ComplexNumber)
- is of the form .
- IMREAL(),returns the real coefficient of a complex number.
is of the form 
.
Description
- This function gives the real coefficient of the complex number.
- In , ComplexNumber is in the form of
- where & are the real numbers. imaginary unit. .
- The complex number can be identified by in the complex plane.
- Here is called real part and is the imaginary part of .
- This function shows the value of the real part of .
- A complex is said to be purely imaginary when and it is a real number when .
- We can use COMPLEX function to convert real and imaginary number in to a complex number.
, ComplexNumber is in the form of 
& 
are the real numbers. 
imaginary unit. 
.
in the complex plane.
.
and it is a real number when 
.ZOS
- The syntax is to calculate real coefficient of the complex number in ZOS is .
- is of the form .
- For e.g.,IMREAL(IMSUM("2+3i","1-9i"))
Examples
- =IMREAL("3+4i") = 3
- =IMREAL("-5+6i") = -5
- =IMREAL("8") = 8
- =IMREAL("-2i") = 0
