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.

Input	SEH Exception	`_matherr` Exception
± ∞, QNAN, IND	none	_DOMAIN
± ∞ (`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>
