This module is home to specific dtypes related functionality and their classes.
|
For more general information about dtypes, also see `numpy.dtype` and
|
:ref:`arrays.dtypes`.
|
|
Similar to the builtin ``types`` module, this submodule defines types (classes)
|
that are not widely used directly.
|
|
.. versionadded:: NumPy 1.25
|
|
The dtypes module is new in NumPy 1.25. Previously DType classes were
|
only accessible indirectly.
|
|
|
DType classes
|
-------------
|
|
The following are the classes of the corresponding NumPy dtype instances and
|
NumPy scalar types. The classes can be used in ``isinstance`` checks and can
|
also be instantiated or used directly. Direct use of these classes is not
|
typical, since their scalar counterparts (e.g. ``np.float64``) or strings
|
like ``"float64"`` can be used.
