NAME
     complex_operators - Operators for the C++ complex math library

SYNOPSIS
     #include <complex.h>

     class complex {

     public:
          friend complex operator+(complex, complex);
          friend complex operator-(complex);
          friend complex operator-(complex, complex);
          friend complex operator*(complex, complex);
          friend complex operator/(complex, complex);

          friend int     operator==(complex, complex);
          friend int     operator!=(complex, complex);

          void operator+=(complex);
          void operator-=(complex);
          void operator*=(complex);
          void operator/=(complex);

     };

DESCRIPTION
     NOTE: This man page applies only to the -o32 ABI.  The MIPSpro -n32
     and -64 ABIs support the template-based complex class which is
     included in the C++ standard library and is automatically loaded by
     the MIPSpro C++ compiler.  The -lm option must still be used to link
     the math library.

     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.

WARNINGS
     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, the following is valid:

          x = ( y + z );

          x = ( y == z );
