ctanh, ctanhf, ctanhl

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
± INF, QNaN, IND	none	_DOMAIN
± INF (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>
