Retrieves the cosine of a complex number.
_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.
The cosine of z, in radians.
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.
