NAME

cxsinhf, cxsinh, cxsinhl, cxsinhw, cxsinhq, cxsinhll, cxsinhdf, cxsinhd, cxsinhdl, cxsinhdll - complex hyperbolic sine function with real arithmetic

SYNOPSIS

cc [ flags ] -I/usr/local/include file(s) -L/usr/local/lib -lmcw [ ... ]

#include <mathcw.h>

#include <cxcw.h>

extern void cxsinhf (cx_float result, cx_float z);

extern void cxsinh (cx_double result, cx_double z);

extern void cxsinhl (cx_long_double result, cx_long_double z);

extern void cxsinhdll (cx_decimal_long_long_double result, cx_decimal_long_long_double z);

NB: Functions with prototypes containing underscores in type names may be available only with certain extended compilers.


DESCRIPTION

Compute the principal value of the complex hyperbolic sine function.

The value of the complex argument z (a two-element array with the real and imaginary parts in that order). is unrestricted.

For finite real-valued arguments, the real function range is [-Infinity, +Infinity].

The cx family of functions provide limited support for complex arithmetic when compiler or language support for a complex type is lacking.


BRANCH CUTS

To be written.

RETURN VALUES

For in-range real arguments, the returned value is in the range [-Infinity, +Infinity]. For finite complex arguments, the returned value is complex and finite. For infinite arguments, at least one component of the returned value is Infinity. Otherwise, for NaN arguments, at least one component of the returned value is a quiet NaN.

ERRORS

For out-of-range, Infinity and NaN arguments, the returned value is a quiet NaN, and errno is set to EDOM.
