This is a PR simpler than #1469 which focuses more on adding FloatingArray.

I have made many more categories for the DtypeArgs, because of the following reasons:

  • Only Pandas dtypes are relevant for making a FloatingArray. Native and Numpy dtypes lead to a NumpyExtensionArray, and PyArrow dtypes lead to an ArrowExtensionArray, if not ArrowStringArray

  • Pandas supports more dtypes in astype than in constructors

  • Index does not support np.float16

  • Closes FloatingArray documented but missing from stubs #1428

  • Tests added
