c99 [ flag... ] file... -lm [ library... ]
#include <math.h>
double sinh(double x);
float sinhf(float x);
long double sinhl(long double x);
These functions compute the hyperbolic sine of x.
Upon successful completion, these functions return the hyperbolic
sine of x.
If the result would cause an overflow, a range error occurs and
+-HUGE_VAL, +-HUGE_VALF, and +-HUGE_VALL (with the same sign as x) is
returned as appropriate for the type of the function.
If x is NaN, a NaN is returned.
If x is +-0 or +-Inf, x is returned.
For exceptional cases, matherr(3M) tabulates the values to be
returned by acos() as specified by SVID3 and XPG3.
These functions will fail if:
Range Error
The result would cause an overflow.
If the integer expression (math_errhandling &
MATH_ERREXCEPT) is non-zero, the overflow floating-
point exception is raised.
The asinh() function sets errno to ERANGE if the
result would cause an overflow.
An application wanting to check for exceptions should call
feclearexcept(FE_ALL_EXCEPT) before calling these functions. On
return, if fetestexcept(FE_INVALID | FE_DIVBYZERO | FE_OVERFLOW |
FE_UNDERFLOW) is non-zero, an exception has been raised. An
application should either examine the return value or check the
floating point exception flags to detect exceptions.
An application can also set errno to 0 before calling asinh(). On
return, if errno is non-zero, an error has occurred. The asinhf() and
asinhl() functions do not set errno.

NAME
sinh, sinhf, sinhl - hyperbolic sine function
SYNOPSIS
c99 [ flag... ] file... -lm [ library... ]
#include <math.h>
double sinh(double x);
float sinhf(float x);
long double sinhl(long double x);
DESCRIPTION
These functions compute the hyperbolic sine of x.
RETURN VALUES
Upon successful completion, these functions return the hyperbolic
sine of x.
If the result would cause an overflow, a range error occurs and
+-HUGE_VAL, +-HUGE_VALF, and +-HUGE_VALL (with the same sign as x) is
returned as appropriate for the type of the function.
If x is NaN, a NaN is returned.
If x is +-0 or +-Inf, x is returned.
For exceptional cases, matherr(3M) tabulates the values to be
returned by acos() as specified by SVID3 and XPG3.
ERRORS
These functions will fail if:
Range Error
The result would cause an overflow.
If the integer expression (math_errhandling &
MATH_ERREXCEPT) is non-zero, the overflow floating-
point exception is raised.
The asinh() function sets errno to ERANGE if the
result would cause an overflow.
USAGE
An application wanting to check for exceptions should call
feclearexcept(FE_ALL_EXCEPT) before calling these functions. On
return, if fetestexcept(FE_INVALID | FE_DIVBYZERO | FE_OVERFLOW |
FE_UNDERFLOW) is non-zero, an exception has been raised. An
application should either examine the return value or check the
floating point exception flags to detect exceptions.
An application can also set errno to 0 before calling asinh(). On
return, if errno is non-zero, an error has occurred. The asinhf() and
asinhl() functions do not set errno.
