polars.datatypes.Decimal

class polars.datatypes.Decimal(precision: int | None = None, scale: int = 0)

Decimal 128-bit type with an optional precision and non-negative scale.

Warning

This functionality is considered unstable. It is a work-in-progress feature and may not always work as expected. It may be changed at any point without it being considered a breaking change.

Parameters:

precision

Maximum number of digits in each number. If set to None (default), the precision is inferred.

scale

Number of digits to the right of the decimal point in each number.

__init__(precision: int | None = None, scale: int = 0) → None
