IMSUB(z1,z2)

This function gives the difference of the two complex numbers.
IMSUB(z1,z2), Where $z1,z2$ are the complex number is of the form $a+ib$ .
$a$ & $b$ are the real numbers. $i$ imaginary unit . $i={\sqrt {-1}}$ .
Let $z1=a+ib$ and </math>z2=c+id</math>.
The difference of two complex number is: $(a+ib)-(c+id)=(a-c)+(b-d)i$ where $a,b,c$ and $d$ are real numbers.
We can use COMPLEX function to convert real and imaginary number in to a complex number.
