**MAKECOMPLEXIMINUS (Real,Imaginary)**

- is the real part of the complex number.
- is the imaginary part of the complex number.

## Description

- MAKECOMPLEXIMINUS function converts the imaginary coefficient of a complex number into 'negative' coefficient.
- 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 squring it gives a negative result.
- For e.g. . Because a negative times a negative is positive.
- A complex number is in the form , where and are real numbers and is the imaginary unit. Where
- To mention and , we must use the lower case only
- In a complex number real part is denoted by & imaginary part is denoted by .
- MAKECOMPLEXIMINUS returns the error value, when and 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.

- =MAKECOMPLEXIMINUS (5,2) gives
- =MAKECOMPLEXIMINUS (5,2,["j"]) gives

## ZOS

- The syntax is to calculate MAKECOMPLEXIMINUS in ZOS is

- is the real part.
- is the imaginary part.

## Examples

- =MAKECOMPLEXIMINUS(4,5) = 4-i5
- =MAKECOMPLEXIMINUS(4,-5) = 4+i5
- =MAKECOMPLEXIMINUS(1,10,"j") = 1-j10
- =MAKECOMPLEXIMINUS(1,0) = 1+i0
- =MAKECOMPLEXIMINUS(1..3,5)
