+Summary: Floating point formatted differently than Rotor
+
+Description of Problem: 
+ 
+When Rotor needs to round a floating-point number for display purposes, it appears 
+to use the "conventional" rounding that most people use rather than the IEEE 
+rounding that Math.Round requires. To be specific, rounding to 3 decimal places, 
+Math.Round would turn 1.234567 into 1.234. However, the rounding for display 
+purposes, triggered by String.Format, rounds 1.234567 to 1.235 for display on 
+Rotor. Mono uses Math.Round for rounding formatted output, so it outputs 1.234. 
+ 
+Test program: 
+ 
+using System; 
+ 
+public class Testing 
+{ 
+        public static void Main() 
+        { 
+                Console.WriteLine( "{0:N3}", 1.234567 ); 
+        } 
+} 
+ 
+ 
+ 
+Steps to reproduce the problem: 
+1. mcs format.cs 
+2. mono format.exe 
+ 
+Actual Results: 
+ 
+1.234 
+ 
+ 
+Expected Results: 
+ 
+1.235 
+ 
+ 
+How often does this happen?  
+ 
+Always
