The sinh() function computes the hyperbolic sine of x.

Upon successful completion, sinh() returns the hyperbolic sine of x.

If the result would cause an overflow, +-HUGE_VAL is returned and errno is set to ERANGE.

If x is NaN, NaN is returned.

For exceptional cases, matherr(3M) tabulates the values to be returned as dictated by Standards other than XPG4.

The sinh() function will fail if:

ERANGE

The result would cause overflow.

An application wishing to check for error situations should set errno to 0 before calling sinh(). If errno is non-zero on return, or the return value is NaN, an error has occurred.
