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