pandera.engines.pandas_engine.Decimal#

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

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

`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`

Methods

`__init__`
`check`	Check that pandera `DataType` are equivalent.
`coerce`	Pure coerce without catching exceptions.
`coerce_value`	Coerce an 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.
