   revision of the `IEEE 754 standard <ieee 754 standard_>`_. It has a sign
   bit, a 5-bit exponent and 11-bit precision (with 10 bits explicitly stored),
   and can represent numbers between approximately ``6.1e-05`` and ``6.5e+04``
   at full precision. This type is not widely supported by C compilers: on a
   at full precision. This type is not widely supported by C compilers:
   it's available as :c:expr:`_Float16` type, if the compiler supports the Annex H
   of the C23 standard.  On a
   typical machine, an unsigned short can be used for storage, but not for math
   operations. See the Wikipedia page on the `half-precision floating-point
   format <half precision format_>`_ for more information.
