I guess you could then regex the number to strip trailing zeroes and periods. But that might require raising the complexity to a General Program Mode template -- I believe formatting comes after functions.

So:

program:

formatted_series = finish_formatting(
    field('series_index'),
    '4.1f',
    '',
    ''
);
stripped_series = re(
    formatted_series,
    '^ \[(.*)[.0]+\]$',
    ' [\1] '
);

# Add together the final result
strcat(
    field('series'),
    stripped_series,
    field('title')
);
