BOOTSTRAP (klibm) functions
LIBRARY ROUTINE
ktan - compute the double precision tangent of the argument.
LIBRARY CALL
double ktan(double x)
INPUT
- x - radian input argument to compute the tangent
on.
OUTPUT
none
RETURN VALUE
the double precision tangent of the input argument
DESCRIPTION
The ktan function computes the tangent of the
input argument.
This is provided in all POSIX and X/OPEN
compliant C math libraries. Currently
ktan is simply a macro to tan 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.
