Sam, there is a bug number 1789 for problems with float conversions. Yes, the
method we use for float is rather brain dead and clearly has bugs. For problems
with integers, I'd like to see your test case.

No it should use a dyanmic buffer when the field size is greater than 40.
FieldLength should match the number of actual digit outputs at the end of
conversion I believe. I should have created test cases against precision at
least (with I64), but if it does not match what you are talking about could you
create one to show a buffer overrun problem?
