Comment:
The validation issue is a bug in `DecimalField`. `DecimalField` calls
`value.as_tuple()` and unconditionally takes the absolute value of the
third argument (`exponent`) as the number of decimal places. This is just
wrong, because it's perfectly valid for exponent to be positive, and in
that case it doesn't represent a number of decimal places at all, it
represents trailing zeros.
The other issue (quantize error) I can't reproduce and I don't think is
related. Please open as a separate ticket with full reproduction
instructions (including version of Python, since that's an error coming
directly from Python's decimal module).
