SINH(3) Linux Programmer's Manual SINH(3)

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():
         _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L
             || /* Since glibc 2.19: */ _DEFAULT_SOURCE
             || /* Glibc versions <= 2.19: */ _BSD_SOURCE || _SVID_SOURCE

DESCRIPTION

     These functions return the hyperbolic sine of x, which is defined math-
     ematically 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 (nega-
     tive 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, POSIX.1-2008.
     The variant returning double also conforms to SVr4, 4.3BSD, C89.
