FloatingPoint
-------------

The CamCOPS client uses Google's FloatingPoint class for “nearly equal”
testing. This is from the Google C++ Testing Framework.

See:

- https://stackoverflow.com/questions/17333/what-is-the-most-effective-way-for-float-and-double-comparison

GNU GPL v3+ (as for CamCOPS). See https://www.qcustomplot.com/.


.. _licence_snomed:

SNOMED CT
---------

CamCOPS does not include SNOMED CT codes, but supports them if a local
administrator is permitted to install them and does so. See :ref:`SNOMED CT
<snomed>`.

The licensing terms are reproduced here for convenience, but the original
should be checked in all situations:

..  literalinclude:: licence_snomed_ct.txt

Note that SNOMED International define a SNOMED CT identifier as:

    "A unique integer identifier applied to each SNOMED CT component (Concept,
    Description, or Relationship)."

Sounds
------

For sounds relating to specific tasks, see each task’s information file. For
the CamCOPS general sounds:

- Sound test 1 (bach_brandenburg_3_3.mp3):

  - excerpt from Bach JS, *Brandenburg
    Concerto No. 3, third movement (Allegro)*, by the Advent Chamber Orchestra,
    from
    `<http://freemusicarchive.org/music/Advent_Chamber_Orchestra/Selections_from_the_2005-2006_Season/>`_;

- Sound test 2 (mozart_laudate.mp3):

Images
------

For images relating to specific tasks, see each task’s information file. For
the CamCOPS general images:

..  Something about URLs makes Sphinx go wrong with e.g.
    WARNING: Block quote ends without a blank line; unexpected unindent.
    The practical answer seems to be to stop word-wrapping the lines in the
    table that complain.
..  More generally, sometimes URLs with underscores in generate errors about
    "bad target name" or similar. Try replacing http://dodgy_url with
    `<http://dodgy_url>`_
