ibm_db_sa: decfloat support #148

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
At time of writing, there is no field mapping in ibm_db_sa for the DB2 DECFLOAT 
type, so they just come back as strings.  decimal.Decimal is the appropriate 
python-side type to map them to, as discussed -

(wonder if it would be possible and a good idea to actually warn if 
decimal.getcontext().prec <34 too, it defaults to 28 but can be raised. It's 
only relevant if python-side arithmetic is then performed I suppose, a created 
Decimal may have more precision than the current context prec, so maybe a 
mention of that issue in the documentation would be sufficient, or even 
unnecessary since it's just how python decimal is and one might expect a dev to 
know that...)
