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);

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

sinhf(), sinhl(): _BSD_SOURCE || _SVID_SOURCE || _XOPEN_SOURCE >= 600 || _ISOC99_SOURCE; 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 floating-point exception (FE_OVERFLOW) is raised.

CONFORMING TO
C99, POSIX.1-2001.  The variant returning double also conforms to SVr4, 4.3BSD, C89.
