+Summary: Double.ToString with format R does not roundtrip
+
+The Mono roundtrip string format of a double doesn't roundtrip.
+
+Execute the following code :
+
+using System;
+using System.Globalization;
+
+public class EntryPoint
+{
+ public static void Main ()
+ {
+   string astring = Math.E.ToString("R", CultureInfo.InvariantCulture);
+   Console.WriteLine("Format R: " + astring);
+
+   double roundtrip = double.Parse(astring, CultureInfo.InvariantCulture);
+   if (Math.E != roundtrip) {
+     Console.WriteLine("Roundtrip format failure");
+   }
+ }
+}
+
+On MS.NET this will result in :
+
+Format R: 2.7182818284590451
+
+On Mono, you'll get :
+
+Format R: 2.71828182845904
+Roundtrip format failure
