BOOTSTRAP (klibm) functions
LIBRARY ROUTINE
kcosh - compute the hyperbolic cosine of the argument.
LIBRARY CALL
double kcosh(double x)
INPUT
- x - input argument to compute the double precision hyperbolic
cosine on.
OUTPUT
none
RETURN VALUE
the double precision hyperbolic cosine of the
input argument or KMAXFLOAT if the
input argument is less than one.
DESCRIPTION
The kcosh function computes the hyperbolic
cosine of the double precison input argument.
This is provided in all POSIX and X/OPEN compliant C
math libraries. Currently kcosh is simply a macro to
cosh because Khoros does not run on any machine whose
math library does not include this function. If
Khoros is ported to a machine without this function
then a replacement will be written.
