[jira] [Created] (GEOMETRY-51) EpsilonDoublePrecisionContext allows negative epsilon

Baljit Singh created GEOMETRY-51:
------------------------------------

             Summary: EpsilonDoublePrecisionContext allows negative epsilon
                 Key: GEOMETRY-51
                 URL: https://issues.apache.org/jira/browse/GEOMETRY-51
             Project: Apache Commons Geometry
          Issue Type: Bug
            Reporter: Baljit Singh


EpsilonDoublePrecisionContext does not validate the epsilon to be positive (0 or greater). The comparison is based on Precision.compareTo(double, double, double), which itself calls Precision.equals(double, double, double), which then compares using Math.abs(y - x) <= eps. If epsilon is negative, the comparison in invalid.
