SINH(3)                   (2017-09-15)                    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);

     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

     DESCRIPTION
          These functions return 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 func-
          tions  return  HUGE_VAL,  HUGE_VALF,  or  HUGE_VALL, respec-
          tively, 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.
