COMPLEXNUMBER (String)

Description

This function is showing the complex number.
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 squaring it gives a negative result.
For e.g. {-4}^2 =16. Because a negative times a negative is positive.
A complex number is a number is in the form $z=a+bi$ , where a and b are real numbers and i is the imaginary unit.
Where $i={\sqrt {-1}}$ .
In $COMPLEXNUMBER(String)$ , $String$ is any complex number.
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.When we assigning without real value it is showing "0" for real value in the complex number.
In the same way it is assigning "0" for imaginary value in the complex number.
