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.
