Retrieves the complex conjugate of a complex number.

Syntax

_Dcomplex conj(   
   _Dcomplex z   
);  
_Fcomplex conj(   
   _Fcomplex z   
);  // C++ only  
_Lcomplex conj(   
   _Lcomplex z   
);  // C++ only  
_Fcomplex conjf(   
   _Fcomplex z   
);  
_Lcomplex conjl(   
   _Lcomplex z   
);

Parameters

z
A complex number.

Return Value

The complex conjugate of z. The result has the same real and imaginary part as z, but with the opposite sign.

Remarks

Because C++ allows overloading, you can call overloads of conj that take and return _Fcomplex and _Lcomplex values. In a C program, conj always takes and returns a _Dcomplex value.

Requirements

Routine	C header	C++ header
`conj`, `conjf`, `conjl`	<complex.h>	<ccomplex>
