Excellent! Thanks a lot for the contribution Derek!

for (int n = -10000; n < 10000; n++)
Assert ( [microsoft's] n.ToString(format) == [mono's] n.ToString(format) )
Could you post your test, or check it into CVS?
With the compiler I have learned to appreciate more and more having a
regression test suite. Right now Ravi and I have a rule of `Do not
check in changes to the compiler in CVS if the test suite fails' which
is really helpful, because it is easy to break something
It is easier to find a bug when you have fresh in your mind the
changes that you have done and can better infer the source of the
problem on far reaching so this has been very helpful for us.

Wow, you have done a great job! i love the IntegerFormatter, thanks a
