Retrieves the inverse hyperbolic cosine of a complex number with a branch cut at values less than 1 along the real axis. .

Syntax

_Dcomplex cacosh(   
   _Dcomplex z   
);  
_Fcomplex cacosh(   
   _Fcomplex z   
);  // C++ only  
_Lcomplex cacosh(   
   _Lcomplex z   
);  // C++ only  
_Fcomplex cacoshf(   
   _Fcomplex z   
);  
_Lcomplex cacoshl(   
   _Lcomplex z   
);

Parameters

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

Return Value

The inverse hyperbolic cosine of z, in radians. The result is unbounded and non-negative along the real axis, and in the interval [−iπ, +iπ] along the imaginary axis.

Remarks

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

Requirements

Routine	C header	C++ header
`cacosh`, `cacoshf`, `cacoshl`	<complex.h>	<ccomplex>
