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

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

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.
