MAKECOMPLEXIPLUS (Real,Imaginary)

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

## Description

• MAKECOMPLEXIPLUS function converts the imaginary coefficient of a complex number into 'positive' 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 a 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 .
• MAKECOMPLEXIPLUS 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.
1. =MAKECOMPLEXIPLUS (5,2) gives 2. =MAKECOMPLEXIPLUS (5,2,["j"]) gives ## ZOS

• The syntax is to calculate MAKECOMPLEXIPLUS in ZOS is • is the real part.
• is the imaginary part.

## Examples

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