*FP16 ARM alternative format*

Type: ``bool``

Help
====

.. code-block:: none

    This option selects the ARM alternative format for FP16.  This
    representation is similar to the IEEE 754-2008 format, but does not
    support infinites or NaNs. Instead, the range of exponents is extended,
    so that this format can represent normalized values in the range of
    2^(-14) to 131008.
