Assigns new values to the contents.

1) Assigns x to the real part of the complex number. Imaginary part is set to zero.

2,3) Assigns cx.real() and cx.imag() to the real and the imaginary parts of the complex number respectively.

x	-	value to assign
cx	-	complex value to assign

*this.

(constructor)	constructs a complex number (public member function)
operator""ifoperator""ioperator""il (C++14)	A `std::complex` literal representing pure imaginary number (function)
