BOOTSTRAP (klibm) functions
LIBRARY ROUTINE
kacosh - compute the arc hyperbolic cosine of the argument.
LIBRARY CALL
double kacosh(double x)
INPUT
OUTPUT
none
RETURN VALUE
the double precision are hyperbolic cosine of the
input argument or KMAXFLOAT if the input argument is
less than one.
DESCRIPTION
The kacosh function computes the arc hyperbolic
cosine of the double precision argument.
kacosh is not a POSIX function, but is
implemented in a few BSD math libraries.
If it is implemented for the current architecture
in libm.a, then this is simply a macro to acosh,
otherwise kasinh is a macro to the Khoros
portable version of acosh.
