Computes the complex hyperbolic tangent of a complex number.

Syntax

_Dcomplex ctanh(   
   _Dcomplex z   
);  
_Fcomplex ctanh(   
   _Fcomplex z   
);  // C++ only  
_Lcomplex ctanh(   
   _Lcomplex z   
);  // C++ only  
_Fcomplex ctanhf(   
   _Fcomplex z   
);  
_Lcomplex ctanhl(   
   _Lcomplex z   
);

Parameters

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

Return Value

The complex hyperbolic 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 ctanh that take and return _Fcomplex and _Lcomplex values. In a C program, ctanh always takes and returns a _Dcomplex value.

Requirements

Routine	C header	C++ header
`ctanh`, `ctanhf`, `ctanhl`	<complex.h>	<ccomplex>
