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.
