I'd like to be able to do:
"bid_price"  :numeric(),
but there is no numeric type around line 546 in orm/columns.py, which I'm
guessing would look like:
# float point quantities
float, floatColumn = _float, _floatColumn
numeric, numericColumn = _float, _floatColumn

Any pointers would be appreciated.

Best regards and thanks again,

Eric Walstad,
