ccos, ccosf, ccosl

Retrieves the cosine of a complex number.

Syntax

_Dcomplex ccos(   
   _Dcomplex z   
);  
_Fcomplex ccos(   
   _Fcomplex z   
);  // C++ only  
_Lcomplex ccos(   
   _Lcomplex z   
);  // C++ only  
_Fcomplex ccosf(   
   _Fcomplex z   
);  
_Lcomplex ccosl(   
   _Lcomplex z   
);  

Parameters

z
A complex number that represents the angle, in radians.

Return Value

The cosine of z, in radians.

Remarks

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

Requirements

Routine	C header	C++ header
ccos, ccosf, ccosl	<complex.h>	<ccomplex>
