+Summary: Bug in Math.Round
+
+Math.Round is broken when called for negative numbers.
+
+This example code show the problem :
+
+using System;
+
+class StringTest
+{
+	static void Main(string[] args)
+	{
+		double test = 2.510;
+		Console.WriteLine("{0}", Math.Round(test));
+		test = 2.490;
+		Console.WriteLine("{0}", Math.Round(test));
+
+		test = -2.510;
+		Console.WriteLine("{0}", Math.Round(test));
+		test = -2.490;
+		Console.WriteLine("{0}", Math.Round(test));
+	}
+}
+
+Should return :
+
+3
+2
+-3
+-2
+
+but with our corlib it gets:
+
+3.0000000
+2.0000000
+-2.0000000
+-2.0000000
+
+(Note that our lib also has different default formating)
