ccosh, ccoshf, ccoshl

Retrieves the hyperbolic cosine of a complex number.

Syntax

_Dcomplex ccosh(
   _Dcomplex z
);
_Fcomplex ccosh(
   _Fcomplex z
);  // C++ only
_Lcomplex ccosh(
   _Lcomplex z
);  // C++ only
_Fcomplex ccoshf(
   _Fcomplex z
);
_Lcomplex ccoshl(
   _Lcomplex z
);

Parameters

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

Return value

The hyperbolic cosine of z, in radians.

Remarks

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

Requirements

Routine	C header	C++ header
ccosh, ccoshf, ccoshl	<complex.h>	<ccomplex>
