r c s& e Zd ZdZd Zd fdd Z ZS )ÚFLOATaF Oracle FLOAT.
|
|
This is the same as :class:`_sqltypes.FLOAT` except that
|
an Oracle-specific :paramref:`_oracle.FLOAT.binary_precision`
|
parameter is accepted, and
|
the :paramref:`_sqltypes.Float.precision` parameter is not accepted.
|
|
Oracle FLOAT types indicate precision in terms of "binary precision", which
|
defaults to 126. For a REAL type, the value is 63. This parameter does not
|
cleanly map to a specific number of decimal places but is roughly
|
equivalent to the desired number of decimal places divided by 0.3103.

Construct a FLOAT
|
|
:param binary_precision: Oracle binary precision value to be rendered
|
in DDL. This may be approximated to the number of decimal characters
|
using the formula "decimal precision = 0.30103 * binary precision".
|
The default value used by Oracle for FLOAT / DOUBLE PRECISION is 126.

|
|
This type has no special Python behavior, except that it subclasses
|
:class:`_types.DateTime`; this is to suit the fact that the Oracle
|
``DATE`` type supports a time value.

Note that only DAY TO SECOND intervals are currently supported.

This is due to a lack of support for YEAR TO MONTH intervals
|
within available DBAPIs.
|
|
:param day_precision: the day precision value. this is the number of

digits to store for the day field. Defaults to "2"
|
:param second_precision: the second precision value. this is the

number of digits to store for the fractional seconds field.

Defaults to "6".
