Gilles commented on MATH-1449:
------------------------------
In the check
{code:java}
Assert.assertEquals(Double.POSITIVE_INFINITY, poly.getSize(), 1e-10);
{code}
using a tolerance looks a bit strange. Shouldn't it rather be
{code:java}
Assert.assertTrue(Double.isInfinite(poly.getSize()));
{code}
?
Also, statements such as
{code:java}
Assert.assertEquals(false, poly.isEmpty());
Assert.assertEquals(true, poly.isFull());
{code}
would read better as
{code:java}
Assert.assertFalse(poly.isEmpty());
Assert.assertTrue(poly.isFull());
{code}
> PolygonsSet.getBarycenter() returns incorrect value for empty region

> Key: MATH-1449
> URL: https://issues.apache.org/jira/browse/MATH-1449
> Project: Commons Math
> Issue Type: Bug
> Affects Versions: 4.0, 3.6
> Reporter: Matt Juntunen
> Priority: Major
> Fix For: 4.0
>
>
> The o.a.c.m.geometry.euclidean.twod.PolygonsSet.getBarycenter() method
> returns the point (0, 0) when the region is empty. It should return (NaN,
> NaN) since the barycenter does not exist. This is the behavior of
> IntervalsSet and PolyhedronsSet.
