Raymond Hettinger <rhettin...@users.sourceforge.net> added the comment:
FWIW, there is a public API to get at the same information:
Decimal.as_tuple().
That being said, I don't see how your len(value._int) test could be
correct. The exponent will potentially shift the value way
out-of-bounds for a database. Consider Decimal('999E+10') or
Decimal('999E-10') whose database storage sizes do not fit in a
DECIMAL(7,4) field eventhough their len(value._int) is three.
To see if the fractional part of a decimal number fits in a database,
set the context precision to the database precision and quantize the
decimal to the allowed number of decimal places. If the Inexact flag
gets set, then it didn't fit.
-1 on extending the API any further from the underlying IBM specification.
