sinh(3M)
NAME
sinh - hyperbolic sine function
SYNOPSIS
cc [ flag ... ] file ... -lm [ library ... ]
#include <math.h>
double sinh(double x);
DESCRIPTION
The sinh() function computes the hyperbolic sine of x.
RETURN VALUES
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.
ERRORS
The sinh() function will fail if:
ERANGE
The result would cause overflow.
USAGE
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.
