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