BOOTSTRAP (klibm) functions


LIBRARY ROUTINE

ktanh - compute the hyperbolic tangent of the argument.

LIBRARY CALL

double ktanh(double x)

INPUT

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.
