BOOTSTRAP (klibm) functions


LIBRARY ROUTINE

kcosh - compute the hyperbolic cosine of the argument.

LIBRARY CALL

double kcosh(double x)

INPUT

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.
