DESCRIPTION
The basic arithmetic operators, comparison operators, and assignment
operators are overloaded for complex numbers. The operators have their
conventional precedences. In the following descriptions for complex
operators,
- x, y, and z are of type complex.
Arithmetic operators:
z = x + y Returns a complex which is the arithmetic sum of complex
numbers x and y.
z = -x Returns a complex which is the arithmetic negation of
complex number x.
z = x - y Returns a complex which is the arithmetic difference of
complex numbers x and y.
z = x * y Returns a complex which is the arithmetic product of
complex numbers x and y.
z = x / y Returns a complex which is the arithmetic quotient of
complex numbers x and y.
Comparison operators:

x == y Returns non-zero if complex number x is equal to complex
number y; returns 0 otherwise.
x != y Returns non-zero if complex number x is not equal to
complex number y; returns 0 otherwise.
Assignment operators:
x += y Complex number x is assigned the value of the arithmetic
sum of itself and complex number y.
x -= y Complex number x is assigned the value of the arithmetic
difference of itself and complex number y.
x *= y Complex number x is assigned the value of the arithmetic
product of itself and complex number y.
x /= y Complex number x is assigned the value of the arithmetic
quotient of itself and complex number y.
WARNING
The assignment operators do not produce a value that can be used in an
expression. That is, the following construction is syntactically
invalid,
complex x, y, z;
x = ( y += z );
whereas,
x = ( y + z );
x = ( y == z );
are valid.
