*COMPLEX function converts the real and imaginary coefficients into a complex number.

*A complex number is a number is  in the form <math> z = a + bi</math>, where a and b are real numbers and <math>i</math> is the imaginary unit. Where <math>i=\sqrt{-1}</math>

*A complex number is a number is  in the form <math> z = a + bi</math>, where <math>a</math> and <math>b</math> are real numbers and <math>i</math> is the imaginary unit. Where <math>i=\sqrt{-1}</math>

*In <math>COMPLEX(rn,in,sf)</math>, here <math>rn</math> is the real part of a complex number, <math>in</math> is the imaginary part of a complex number and <math>sf</math> is the imaginary unit of a complex number like <math>i</math> or <math>j</math>.

*In <math>COMPLEX(rn,in,sf)</math>, here <math>rn</math> is the real part of a complex number, <math>in</math> is the imaginary part of a complex number and <math>sf</math> is the imaginary unit of a complex number like <math>i</math> or <math>j</math>.

*To mention <math>i</math> and <math>j</math>, we must use the lower case only
