GETREALORCOMPLEX (x,y)

where

and are any real numbers.
- GETREALORCOMPLEX() converts the real and imaginary numbers into a complex number.

Description

A complex number is a combination of a real and an imaginary number.
A number which is positive or negative, rational or irrational or decimals are called real numbers.
An Imaginary number is a number that when squaring it gives a negative result.
For e.g. ${-4}^{2}$ =16. Because a negative times a negative is positive.
A complex number is a number is in the form $z=a+bi$ , where $a$ and $b$ are real numbers and $i$ is the imaginary unit. Where $i={\sqrt {-1}}$ .

GETREALORCOMPLEX (x,y)

$x$ is the real part of the complex number, $y$ is the imaginary part of the complex number.
Here suffix value is considered as $i$ .
This function returns the error value, when real and imaginary are non-numeric.
A Complex number whose real part is zero is said to be purely imaginary.
A Complex number whose imaginary part is zero is a real number.
In that cases we have to assign '0' for that part.
