ctan, ctanf, ctanl

Retrieves the tangent of a complex number.

Syntax

_Dcomplexctan( _Dcomplexz ); _Fcomplexctan( _Fcomplexz ); // C++ only_Lcomplexctan( _Lcomplexz ); // C++ only_Fcomplexctanf( _Fcomplexz ); _Lcomplexctanl( _Lcomplexz );

Parameters

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

Return value

The tangent of z.

Input	SEH exception	_matherr exception
± INF, QNaN, IND	none	_DOMAIN
± INF (tan, tanf)	INVALID	_DOMAIN

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.

Requirements

Routine	C header	C++ header
ctan, ctanf, ctanl	<complex.h>	<ccomplex>
