IMCONJUGATE(z)

This function gives the conjugate of a complex number.
The complex number $z=a+bi$ , then $IMCONJUGATE(a+bi)=z(bar)=a-bi$ and it is denoted by ${\bar {z}}$ or $z^{*}$ .
So complex number and complex conjugate both also having same real number and imaginary number with

the equal magnitude and opposite sign of a imaginary number.Also

$z={\bar {z}}$ if imaginary number is '0' and $z={\bar {\bar {z}}}=z$
$|{\bar {z}}|=|z|$ and $|z|^{2}=z.{\bar {z}}={\bar {z}}.z$
$Realpart(a)={\frac {z+{\bar {(}}z))}{2}}$
Imaginary part (b)=z-z(bar)/2i.We can use COMPLEX function to convert the real and imginary coefficients to a complex number.
