sinh - Hyperbolic sine

SYNOPSIS

       float sinh (float  $arg)

DESCRIPTION

PARAMETERS

	      o $arg
		- The argument to process

RETURN VALUES

	The hyperbolic sine of $arg

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 floating-point exception (FE_OVERFLOW) is raised.

CONFORMING TO

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