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

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
The following errors can occur:
Range error: result overflow
errno
is set to
ERANGE .
An overflow floating-point exception
(FE_OVERFLOW )
is raised.
CONFORMING TO
C99, POSIX.1-2001.
The variant returning
double
also conforms to
SVr4, 4.3BSD, C89.
