GETREALORCOMPLEX (x,y)

• $x$ and $y$ 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. ${-4}^{2}$ =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 $i={\sqrt {-1}}$.
• In $GETREALORCOMPLEX(x,y)$,$x$ 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.

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
