Hi,
I have found what appears to be a (floating) bug in RectangleF.
Consider the following code
var intersection = RectangleF.Intersect(bigRectangle,subRectangle);
and the following values (this values i'm copying from a debugging session)
bigRectangle: {{X=0,Y=0,Width=320,Height=220}}
subRectangle: {{X=142.9166,Y=139.0106,Width=33.29966,Height=35.14964}}
we get
intersection:{{X=142.9166,Y=139.0106,Width=33.29965,Height=35.14964}}
Note that subRectangle and intersection differ in the last decimal of
the Width property.
>From this follows that RectangleF.Contains(bigRectangle,subRectangle)
returns the wrong value. Here is the code of RectangleF.Contains for
reference.
public bool Contains (RectangleF rect)
{
return rect == RectangleF.Intersect (this, rect);
}
Am I missing something here ? It may be that this was working properly
and stopped working after one of the recent monotouch upgrades.
Thanks,
