12       float sinhf(float x);
13       long double sinhl(long double x);

DESCRIPTION

25       The sinh() function returns the hyperbolic sine of x, which is  defined
26       mathematically as:
27
28           sinh(x) = (exp(x) - exp(-x)) / 2
29

RETURN VALUE

31       On success, these functions return the hyperbolic sine of x.
32
33       If x is a NaN, a NaN is returned.
34
35       If x is +0 (-0), +0 (-0) is returned.
36
37       If x is positive infinity (negative infinity), positive infinity (nega‐
38       tive infinity) is returned.
39
40       If the result overflows, a range error occurs, and the functions return
41       HUGE_VAL,  HUGE_VALF, or HUGE_VALL, respectively, with the same sign as
42       x.
43

ERRORS

45       See math_error(7) for information on how to determine whether an  error
46       has occurred when calling these functions.
47
48       The following errors can occur:
49
50       Range error: result overflow
51              errno  is  set  to ERANGE.  An overflow floating-point exception
52              (FE_OVERFLOW) is raised.
53

CONFORMING TO

55       C99, POSIX.1-2001.  The variant returning double also conforms to SVr4,
56       4.3BSD, C89.
