NAME
sinh, sinhf,
sinhl —
hyperbolic sine functions
SYNOPSIS
#include
<math.h>
double
sinh(double
x);
float
sinhf(float
x);
long double
sinhl(long
double x);
DESCRIPTION
The
sinh()
function computes the hyperbolic sine of x. The
sinhf()
function is a single precision version of sinh().
The
sinhl()
function is an extended precision version of
sinh().
RETURN VALUES
The sinh(),
sinhf() and sinhl()
functions return the hyperbolic sine value unless the magnitude of
x is too large; in this event, the global variable
errno is set to ERANGE.

STANDARDS
The sinh() function conforms to
ANSI X3.159-1989
(“ANSI C89”).
HISTORY
The sinh() function first appeared in
Version 7 AT&T UNIX.
