cudf.core.dtypes.Decimal128Dtype.from_arrow#

classmethod Decimal128Dtype.from_arrow(typ: pa.Decimal128Type) → Self[source]#

Construct a cudf decimal dtype from a pyarrow dtype

Examples

>>> import cudf
>>> import pyarrow as pa
>>> pa_type = pa.decimal128(precision=9, scale=2)

Constructing a Decimal32Dtype:

>>> cudf.Decimal32Dtype.from_arrow(pa_type)
Decimal64Dtype(precision=9, scale=2)

Constructing a Decimal64Dtype:

>>> cudf.Decimal64Dtype.from_arrow(pa_type)
Decimal64Dtype(precision=9, scale=2)

Constructing a Decimal128Dtype:

>>> cudf.Decimal128Dtype.from_arrow(pa_type)
Decimal128Dtype(precision=9, scale=2)
