.Sh NAME
|
|
.Nm sinh ,
|
|
.Nm sinhf
|
|
.Nd hyperbolic sine function
|
|
.Sh SYNOPSIS
|
|
.Fd #include <math.h>
|
|
.Ft double
|
|
.Fn sinh "double x"
|
|
.Ft float
|
|
.Fn sinhf "float x"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Fn sinh
|
|
and the
|
|
.Fn sinhf
|
|
functions compute the hyperbolic sine of
|
|
.Fa x .
|
|
.Sh RETURN VALUES
|
|
The
|
|
.Fn sinh
|
|
and the
|
|
.Fn sinhf
|
|
functions return 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 .
