NAME

6       sinh, sinhf, sinhl - hyperbolic sine function

SYNOPSIS

9       #include <math.h>
10
11       double sinh(double x);
12       float sinhf(float x);
13       long double sinhl(long double x);

18
19       sinhf(), sinhl(): _BSD_SOURCE || _SVID_SOURCE || _XOPEN_SOURCE >= 600

DESCRIPTION

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

RETURN VALUE

29       On success, these functions return the hyperbolic sine of x.
30
31       If x is a NaN, a NaN is returned.
32
33       If x is +0 (-0), +0 (-0) is returned.
34
35       If x is positive infinity (negative infinity), positive infinity (nega‐
36       tive infinity) is returned.
37
38       If the result overflows, a range error occurs, and the functions return
39       HUGE_VAL,  HUGE_VALF, or HUGE_VALL, respectively, with the same sign as
40       x.
41

ERRORS

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

CONFORMING TO

53       C99, POSIX.1-2001.  The variant returning double also conforms to SVr4,
54       4.3BSD, C89.
