within? relation doesn't seem to be working with decimal coordinates

user=> (let [x (point (c 92 8)) pp (polygon (linear-ring [(c 85 0), (c 90 10), (c 100 0), (c 85 0)]) nil)] (cljts.relation/touches? x pp))
true
;; above coordinates divided by 100
user=> (let [x (point (c 0.92 0.08)) pp (polygon (linear-ring [(c 0.85 0.0), (c 0.90 0.10), (c 1.0 0.0), (c 0.85 0.0)]) nil)] (cljts.relation/touches? x pp))
false

Actually, the problem exists (see eg above). There seems a precision issue with jts lib?

I think so. Tested with latest JTS and different PrecisionModel, the result is identical. Does JTS have an issue board or mailing-list for this?
