-Module name
------------

-The chosen name seems consistent with one existing domain-specific mathematical module:

-We note the `Imath
-<https://github.com/AcademySoftwareFoundation/Imath>`_ C++ library includes
-Python bindings with the same name.  There is also an :pypi:`imath` project on
-PyPI, but only with two releases, with the most recent one four years ago.  Its
-repository is no longer accessible.

-`Polling showed <https://discuss.python.org/t/91337/35>`_ ``intmath`` as another
-popular name.  The argument made was that the normal mathematical spelling of
-the imaginary unit is ``i``, which makes ``imath`` ambiguous.  It also has no conflict
-with any PyPI module.  On the other hand, ``intmath`` may be confused with
-interval math or numerical integration.

-Other proposed names include ``ntheory`` (like SymPy's submodule),

-As a variant, the new module can be added as a submodule of the

 There was a brief discussion about exposing :external+py3.14:func:`math.isqrt`
 as ``imath.sqrt`` in the same way that :external+py3.14:func:`cmath.sqrt` is
 the complex version of :external+py3.14:func:`math.sqrt`.  However, ``isqrt``
