pandera.engines.pandas_engine.Decimal

class pandera.engines.pandas_engine.Decimal(precision=28, scale=0, rounding=None)

Semantic representation of a decimal.Decimal.

Note

decimal.Decimal is especially useful when exporting a pandas DataFrame to parquet files via pyarrow. Pyarrow will automatically convert the decimal objects contained in the object series to the corresponding parquet Decimal type.

Attributes

auto_coerce	Whether to force coerce to be True in all cases
continuous	Whether the number data type is continuous.
exact	Whether the data type is an exact representation of a number.
precision	The number of significant digits that the decimal type can represent.
scale	The number of digits after the decimal point.
type	Native pandas dtype boxed by the data type.
rounding	The rounding mode supported by the Python decimal.Decimal class.

Methods

__init__
check	Check that pandera DataType are equivalent.
coerce	Pure coerce without catching exceptions.
coerce_value	Coerce a value to a particular type.
try_coerce	Coerce data container to the data type, raises a ParserError if the coercion fails :raises: ParserError: if coercion fails
__call__	Coerce data container to the data type.
