Data type routines

`dpnp.can_cast`	Returns `True` if cast between data types can occur according to the casting rule.
`dpnp.result_type`	result_type(*arrays_and_dtypes)

Creating data types

dtype(dtype, align=False, copy=False, [metadata])

`dpnp.finfo`	Returns machine limits for floating-point data types.
`dpnp.iinfo`	Returns machine limits for integer data types.

`dpnp.isdtype`	Returns a boolean indicating whether a provided dtype is of a specified data type kind.
`dpnp.issubdtype`	Returns `True` if the first argument is a type code lower/equal in type hierarchy.
