Methods by which we can instantiate a complex number

Question

What are the methods by which we can instantiate a complex number?

Answer 1

The different methods to allot a value to a complex number are as follows:

a.) By passing two Double values to the constructor. The first value will symbolize the real, and second value symbolizes imaginary part of the complex number.
Like:
Complex c1 = new Complex(5, 8); /* It represents (5, 8) */

b.) By casting a BigInteger or Decimal value to a Complex object.
Like:
Complex c3 = (Complex) 14.7; /* It represents (14.7, 0) */

c.) By assigning a value returned by the operator to the Complex variable.
Like:
Complex c4 = c1 + c2; /* It represents (20.3, 8) */

d.) Assigning a Intl6, Byte, UInt64, SByte, Int32, UIntl6, UInt32, Int64, Double or Single value to a Complex object. The allotted value symbolizes a real part of the complex number, and the imaginary part becomes 0. Like:
Complex c2 = 15.3; /* It represents (15.3, 0) */
