* ``divide(x, y)`` -- returns ``x / y``. Throws an exception if either ``x`` or ``y`` are not numbers. This function can usually be replaced by the ``/`` operator.
* ``eval(string)`` -- evaluates the string as a program, passing the local variables. This permits using the template processor to construct complex results from local variables. In :ref:`Template Program Mode <template_mode>`, because the `{` and `}` characters are interpreted before the template is evaluated you must use `[[` for the `{` character and `]]` for the ``}`` character. They are converted automatically. Note also that prefixes and suffixes (the `|prefix|suffix` syntax) cannot be used in the argument to this function when using :ref:`Template Program Mode <template_mode>`.
* ``extra_file_size(file_name)`` -- returns the size in bytes of the extra file ``file_name`` in the book's ``data/`` folder if it exists, otherwise ``-1``. See also the functions ``has_extra_files()``, ``extra_file_names()`` and ``extra_file_modtime()``. This function can be used only in the GUI.
* ``extra_file_modtime(file_name, format_date)`` -- returns the modification time of the extra file ``file_name`` in the book's ``data/`` folder if it exists, otherwise ``-1``. The modtime is formatted according to ``format_string`` (see ``format_date()`` for details). If ``format_string`` is the empty string, returns the modtime as the floating point number of seconds since the epoch. See also the functions ``has_extra_files()``, ``extra_file_names()`` and ``extra_file_size()``. The epoch is OS dependent. This function can be used only in the GUI.
* ``extra_file_modtime(file_name, format_spec)`` -- returns the modification time of the extra file ``file_name`` in the book's ``data/`` folder if it exists, otherwise ``-1``. The modtime is formatted according to ``format_spec`` (see ``format_date()`` for details). If ``format_spec`` is the empty string, returns the modtime as the floating point number of seconds since the epoch. See also the functions ``has_extra_files()``, ``extra_file_names()`` and ``extra_file_size()``. The epoch is OS dependent. This function can be used only in the GUI.
* ``extra_file_names(sep)`` -- returns a ``sep``-separated list of extra files in the book's ``data/`` folder. See also the functions ``has_extra_files()``, ``extra_file_size()`` and ``extra_file_modtime()``. This function can be used only in the GUI.
* ``field(lookup_name)`` -- returns the value of the metadata field with lookup name ``lookup_name``.
* ``field_exists(field_name)`` -- checks if a field (column) with the lookup name ``field_name`` exists, returning ``'1'`` if so and the empty string if not.
