This function will convert a real and imaginary coefficient into a complex number in the form of a+bi.
Where a and b is a real numbers. “i or j” is an imaginary number.
A is a real part, and bi is an imaginary part.
The sample complex numbers are 2+3i and 4-2i.

Here, you will see the syntax of the COMPLEX function.
To apply this function on your spreadsheet, you must select a cell and enter the formula in the following format.
Once you enter the formula, click the Enter button to get the result.

Parameters Description:

Real_num – It is the real coefficient of the complex number.
I_num – It is the imaginary coefficient of the complex number.
The suffix – This is optional. It is the suffix for the imaginary component of the complex number. If it is not mentioned, it will assign “i” automatically.

Note:
1) If either a real_num or i_num is a non-numeric, it returns #VALUE! Error.
2) If the suffix is neither “i” nor “j“, it returns #VALUE! Error.

Examples
