NAME

sinh, sinhf, sinhl - hyperbolic sine function  

SYNOPSIS

#include <math.h>double sinh(double x);
float sinhf(float x);
long double sinhl(long double x);

Link with -lm.

Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

sinhf(), sinhl():

_ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L
    || /* Since glibc 2.19: */ _DEFAULT_SOURCE
    || /* Glibc versions <= 2.19: */ _BSD_SOURCE || _SVID_SOURCE
 

DESCRIPTION

These functions return the hyperbolic sine of x, which is defined mathematically as:
    sinh(x) = (exp(x) - exp(-x)) / 2
 

RETURN VALUE

On success, these functions return the hyperbolic sine of x.

If xis a NaN, a NaN is returned.

If xis +0 (-0), +0 (-0) is returned.

If xis positive infinity (negative infinity), positive infinity (negative infinity) is returned.

If the result overflows, a range error occurs, and the functions return HUGE_VAL, HUGE_VALF, or HUGE_VALL, respectively, with the same sign as x.  

ERRORS

See math_error(7) for information on how to determine whether an error has occurred when calling these functions.

The following errors can occur:

Range error: result overflow
errnois set to ERANGE. An overflow floating-point exception (FE_OVERFLOW) is raised.
