cudf.Index.astype

Index.astype(dtype, copy: bool = True)

Create an Index with values cast to dtypes.

The class of a new Index is determined by dtype. When conversion is impossible, a ValueError exception is raised.

Parameters:

dtypenumpy.dtype

Use a numpy.dtype to cast entire Index object to.

copybool, default False

By default, astype always returns a newly allocated object. If copy is set to False and internal requirements on dtype are satisfied, the original data is used to create a new Index or the original Index is returned.

Returns:

Index

Index with values cast to specified dtype.

Examples

>>> import cudf
>>> index = cudf.Index([1, 2, 3])
>>> index
Index([1, 2, 3], dtype='int64')
>>> index.astype('float64')
Index([1.0, 2.0, 3.0], dtype='float64')
