sinhcosh(3M) sinhcosh(3M)

(Itanium(R)-based System Only)

NAME

sinhcosh( ), sinhcoshf( ), sinhcoshl( ), sinhcoshw( ), sinhcoshq( ) - functions that compute both hyperbolic

sine and hyperbolic cosine

SYNOPSIS

#include <math.h>

void sinhcosh(double x, double *sptr, double *cptr);

void sinhcoshf(float x, float *sptr, float *cptr);

void sinhcoshl(long double x, long double *sptr, long double *cptr);

void sinhcoshw(extended x, extended *sptr, extended *cptr);

void sinhcoshq(quad x, quad *sptr, quad *cptr);

DESCRIPTION

These functions are available only for Itanium-based systems.

sinhcosh() stores the hyperbolic sine of x in the object pointed to by sptr and stores the hyperbolic

cosine of x in the object pointed to by cptr.

sinhcoshf() is a float version of sinhcosh(); it takes float and float * arguments.

sinhcoshl() is a long double version of sinhcosh(); it takes long double and long

double * arguments.

sinhcoshw() is an extended version of sinhcosh(); it takes extended and extended * argu-

ments.

sinhcoshq() is equivalent to sinhcoshl() on HP-UX systems.

USAGE

To use these functions compile either with the default

-Ae option or with the

-Aa and the

-D_HPUX_SOURCE options.

To use

sinhcoshw() or sinhcoshq(), compile also with the -fpwidetypes option.

To use any of these functions, make sure your program includes

<math.h>, and link in the math library

by specifying -lm on the compiler or linker command line.

RETURN VALUE

sinhcosh(±0,sptr,cptr) stores ±0 in the object pointed to by sptr and 1 in the object pointed to by

cptr.

If x is ±INFINITY,

sinhcosh() stores ±INFINITY respectively in the object pointed to by

sptr and

stores +INFINITY in the object pointed to by

cptr.

If x is NaN,

sinhcosh() stores NaN in the objects pointed to by its pointer arguments.

When it raises no other exception, whether

sinhcosh() raises the inexact exception is unspeciﬁed.

ERRORS

No errors are deﬁned.
