BOOTSTRAP (klibm) functions
LIBRARY ROUTINE
kacos - compute the arc cosine of the argument.
LIBRARY CALL
double kacos(double x)
INPUT
- x - input argument to take arc cosine of.
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.
