 * ``fractional_part(x)`` -- returns the value after the decimal point. For example, ``fractional_part(3.14)`` returns ``0.14``. Throws an exception if ``x`` is not a number.
 * ``has_cover()`` -- return ``'Yes'`` if the book has a cover, otherwise the empty string.
 * ``has_extra_files([pattern])`` -- returns the count of extra files, otherwise '' (the empty string). If the optional parameter ``pattern`` (a regular expression) is supplied then the list is filtered to files that match ``pattern`` before the files are counted. The pattern match is case insensitive. See also the functions ``extra_file_names()``, ``extra_file_size()`` and ``extra_file_modtime()``. This function can be used only in the GUI.
-* ``identifier_in_list(val, id_name [, found_val, not_found_val])`` -- treat ``val`` as a list of identifiers separated by commas. An identifier has the format ``id_name:value``. The ``id_name`` parameter is the id_name text to search for, either ``id_name`` or ``id_name:regexp``. The first case matches if there is any identifier matching that id_name. The second case matches if id_name matches an identifier and the regexp matches the identifier's value. If ``found_val`` and ``not_found_val`` are provided then if there is a match then return ``found_val``, otherwise return ``not_found_val``. If ``found_val`` and ``not_found_val`` are not provided then if there is a match then return the ``indentfier:value`` pair, otherwise the empty string (``''``).
+* ``identifier_in_list(val, id_name [, found_val, not_found_val])`` -- treat ``val`` as a list of identifiers separated by commas. An identifier has the format ``id_name:value``. The ``id_name`` parameter is the id_name text to search for, either ``id_name`` or ``id_name:regexp``. The first case matches if there is any identifier matching that id_name. The second case matches if id_name matches an identifier and the regexp matches the identifier's value. If ``found_val`` and ``not_found_val`` are provided then if there is a match then return ``found_val``, otherwise return ``not_found_val``. If ``found_val`` and ``not_found_val`` are not provided then if there is a match then return the ``identifier:value`` pair, otherwise the empty string (``''``).
 * ``is_marked()`` -- check whether the book is `marked` in calibre. If it is then return the value of the mark, either ``'true'`` (lower case) or a comma-separated list of named marks. Returns ``''`` (the empty string) if the book is not marked. This function works only in the GUI.
 * ``language_codes(lang_strings)`` -- return the `language codes <https://www.loc.gov/standards/iso639-2/php/code_list.php>`_ for the language names passed in `lang_strings`. The strings must be in the language of the current locale. ``Lang_strings`` is a comma-separated list.
 * ``list_contains(value, separator, [ pattern, found_val, ]* not_found_val)`` -- (Alias of ``in_list``) Interpreting the value as a list of items separated by ``separator``, evaluate the ``pattern`` against each value in the list. If the ``pattern`` matches any value then return ``found_val``, otherwise return ``not_found_val``. The ``pattern`` and ``found_value`` can be repeated as many times as desired, permitting returning different values depending on the search. The patterns are checked in order. The first match is returned. Aliases: ``in_list()``, ``list_contains()``
