/*
* A complex number can be represented as a paired real number with
* imaginary unit; a+bi. Where a is real part, b is imaginary part
* and i is imaginary unit. Real a equals complex a+0i
* mathematically.
*
* In ruby, you can create complex object with Complex, Complex::rect,
* Complex::polar or to_c method.
*
* Complex(1) #=> (1+0i)
* Complex(2, 3) #=> (2+3i)
* Complex.polar(2, 3) #=> (-1.9799849932008908+0.2822400161197344i)
* 3.to_c #=> (3+0i)
*
* You can also create complex object from floating-point numbers or
* strings.
*
* Complex(0.3) #=> (0.3+0i)
* Complex('0.3-0.5i') #=> (0.3-0.5i)
* Complex('2/3+3/4i') #=> ((2/3)+(3/4)*i)
* Complex('1@2') #=> (-0.4161468365471424+0.9092974268256817i)
*
* 0.3.to_c #=> (0.3+0i)
* '0.3-0.5i'.to_c #=> (0.3-0.5i)
* '2/3+3/4i'.to_c #=> ((2/3)+(3/4)*i)
* '1@2'.to_c #=> (-0.4161468365471424+0.9092974268256817i)
*
* A complex object is either an exact or an inexact number.
*
* Complex(1, 1) / 2 #=> ((1/2)+(1/2)*i)
* Complex(1, 1) / 2.0 #=> (0.5+0.5i)
