Returns the atanh of x to a multiple of eps with error less in
absolute value than .75 * eps.
atanh(x) = ln((1 + x)/(1 - x))/2 is the real number v for whichi
tanh(v) = x.
atanh(x) is the real number v for which tanh(v) = x. It is given by
atanh(x) = ln((1 + x)/(1 - x))/2
EXAMPLE
> print atanh(.5,1e-5), atanh(.5,1e-10), atanh(.5,1e-15), atanh(.5,1e-20)
