ctan, ctanf, ctanl

Retrieves the tangent of a complex number.

Syntax

_Dcomplex ctan(
   _Dcomplex z
);
_Fcomplex ctan(
   _Fcomplex z
);  // C++ only
_Lcomplex ctan(
   _Lcomplex z
);  // C++ only
_Fcomplex ctanf(
   _Fcomplex z
);
_Lcomplex ctanl(
   _Lcomplex z
);

Parameters

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

Return value

The tangent of z.

Remarks

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