BOOTSTRAP (klibm) functions


LIBRARY ROUTINE

kacos - compute the arc cosine of the argument.

LIBRARY CALL

double kacos(double x)

INPUT

OUTPUT

none

RETURN VALUE

the double precision arc cosine of the double precision input argument.

DESCRIPTION

The kacos function computes the arc cosine of the double precision input argument.

This is provided in all POSIX and X/OPEN compliant C math libraries. Currently kacos is simply a macro to acos 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.
