+Summary: About the double comparishon internals.
+Comparing any double value with Double.NaN should always return false. In
+mono it works fine for the absolute comparators (<, >, ==) but it doesn't
+work right for the partial comparators (<=, >=).
+I attach a little test for this mistake. Running this test it shouldn't
+print any message on the console but in mono it prints the following:
+NAN <= 1.0
+NAN >= 1.0
+1.0 <= NAN
+1.0 >= NAN
+If anyone can help me to find out the file that has the implementation of
+the double comparators... email me: <yoros@wanadoo.es>
