Excel IMAGINARY function
The IMAGINARY function returns the imaginary coefficient of a given complex number in the form x + yi or x + yj.
Note: A complex number is composed of a real coefficient and an imaginary coefficient. You can apply the COMPLEX function to convert real and imaginary coefficients to a complex number of the form x + yi or x + yj.
Syntax
IMAGINARY(inumber)
Arguments
- Inumber (required): The complex number for which you want to return the imaginary coefficient.
Remarks
Return value
It returns a numeric value.
Example
In the following table, there is a list of complex numbers. To get the imaginary coefficients of these complex numbers, you can apply the IMAGINARY function as follows to get it done.
