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():

_BSD_SOURCE  _SVID_SOURCE  _XOPEN_SOURCE >= 600  _ISOC99_SOURCE 
_POSIX_C_SOURCE >= 200112L;
or
cc std=c99
DESCRIPTION
The
sinh()
function returns 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
x
is a NaN, a NaN is returned.
If
x
is +0 (0), +0 (0) is returned.
If
x
is 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

errno
is set to
ERANGE.
An overflow floatingpoint exception
(FE_OVERFLOW)
is raised.
CONFORMING TO
C99, POSIX.12001.
The variant returning
double
also conforms to
SVr4, 4.3BSD, C89.
