.Sh SYNOPSIS
|
|
.In math.h
|
|
.Ft double
|
|
.Fn sinh "double x"

|
.Sh DESCRIPTION
|
|
The
|
|
.Fn sinh
|
|
function computes the hyperbolic sine of
|
|
.Fa x .
|
|
.Sh RETURN VALUES
|
|
The
|
|
.Fn sinh
|
|
function returns the hyperbolic sine value unless
|
|
the magnitude of
|
|
.Fa x
|
|
is too large; in this event, the global variable
|
|
.Va errno
|
|
is set to
|
|
.Er ERANGE .
