MAKECOMPLEXIMINUS (Real,Imaginary)

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. ${-4}^{2}=16$ . Because a negative times a negative is positive.
A complex number is in the form $z=a+bi$ , where $a$ and $b$ are real numbers and $i$ is the imaginary unit. Where $i={\sqrt {-1}}$
To mention $i$ and $j$ , we must use the lower case only
In a complex number $z$ real part is denoted by $Re(z)$ & imaginary part is denoted by $Im(z)$ .
MAKECOMPLEXIMINUS returns the error value, when $real$ and $imaginary$ are non-numeric.
$Suffix$ should be either $i$ or $j$ , otherwise it shows error value.
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.

$MAKECOMPLEXIMINUS(Real,Imaginary)$

=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) = 1-i5 ; 2-i5; 3-i5
