If you find bugs, please send me test cases I can use to reproduce and add to the unit test suite. One test per line, like “input”, “format”, “expected” is best. For example, this is a great test case:
-1, "#,#.00", "-1.00"
I can plug that directly into the unit test suite, run it, and if it gives back “-01.00″ it will fail the test. This makes it much easier and more convenient for me to fix bugs.
Sponsoring bug fixes wouldn’t hurt either ;-)
