GETREALORCOMPLEX (x,y)

• and are any real numbers .

## Description

• This function converts the real and imaginary numbers into a complex number.
• 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. =16. Because a negative times a negative is positive.
• A complex number is a number is in the form , where and are real numbers and is the imaginary unit. Where .
• In , is the real part of the complex number, is the imaginary part of the complex number.
• Here suffix value is considered as $\displaystyle ""i""$ .
• 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.

## Examples

1. GETREALORCOMPLEX(9,3) = 9+ⅈ3
2. GETREALORCOMPLEX(12,-90) = 12-ⅈ90
3. GETREALORCOMPLEX(5.2,-3.1) = 5.2-ⅈ3.1
4. GETREALORCOMPLEX(-11,-12) = -11-ⅈ12
