+Summary: Integer/Floating point formatters need to be rewritten.
+
+The current Integer and Floating point formatters do not match the 
+functionality in output of .NET and contain several bugs.
+
+The worst part is that fixing the bugs is fairly complicated due to the
+code structure.  
+
+A new implementation should begin with an extensive test suite of numbers,
+formats and the expected output.
+
+Surprisingly the code to format numbers in Mono (Integer+Floating point)
+than the Gnumeric number formatter and the Gnumeric formatter has to 
+do more as Excel supports many more rendering styles, conditions and
+even coloring.
+
+The gnumeric code could be used for inspiration, as the formatting rules
+are surprisngly similar (including the n-section rendering) and lives
+in gnumeric/src/format.c
+
+The details (and some poor samples) are available in the .NET docs, as:
+
+.NET Framework SDK/
+  Programming with the .NET Framework/
+    Working with Base Types/
+      Formatting Types/
+        Numeric Format Strings/
+
+The samples are poor, that is why various tests are needed to get the
+same behavior, it seems to be inspired by Excel, so Gnumeric might prove
+useful, for a small catalog, see: Format/Cells, then select "Custom"
+formatting from the list.
