Arithmetic operators

The basic arithmetic operators +, (unary and binary), /, and , the assignment operators =, +=, =, =, and /=, as well as the equality operators == and !=, can be used for complex numbers. The operators have their conventional precedences. For example: a=b*c+d for complex variables a, b, c, and d is equivalent to a=(bc)+d. There are no operators for exponentiation and conjugation; instead the functions pow() and conj() are provided. The operators +=, =, =, and /= do not produce a value that can be used in an expression; thus the following examples will cause compile time errors:

   complex a, b;
   // ...
   if ( (a+=2)==0 ) {	//error
   	// ...
   }
   b = a *= b;	//error
