The LaTeX-package ``fcolumn''

In financial reports, text and currency amounts are regularly put in
one table, e.g., a year balance or a profit-and-loss overview.
This package provides the settings for automatically typesetting
such columns, including the sum line (preceded by a rule of the correct
width), using the specifier ``f''.

The column specifier f itself is rather simple.  It is the predefined
version of a generic column F.  The generic version expects three 
arguments: |#1| is the separator, |#2| is the decimal mark, and |#3| 
the coding used for grouping digits of the integer part and decimal
part.  For example the f-column in the current version of the package
is using 3.2 as #3, meaning that numbers are typeset with 2 decimal 
digits and grouping is done on 3 digits.  The decimal separator is 
``,'' and the grouping character is ``.'', thereby coding for the 
continental European standard.  People in the Anglo-saxon world would
rather code |\newcolumntype{f}{F{,}{.}{3,2}}|.

To show where and how the f-column is used, let's look at a typical
financial table.

properties    31 dec 2014   debts         31 dec 2014
-----------------------------------------------------
house          200.000,00   equity capital  50.000,00
bank account      -603,23   mortgage       150.000,00
savings         28.000,00                           
cash               145,85   profit          27.542,62
               ----------                  ----------
               227.542,62                  227.542,62

The core part of the table is input as 
\begin{table}
\begin{tabular}{lflf}
house    &      20000000 &  equity capital &  5000000\\
bank account &    -60323 &  mortgage     &   15000000\\
savings     &    2800000\\
cash         &     14585 &  profit         &  2754262\\
\sumline
\end{tabular}
\end{table}

The column specifier ``f'' (for ``finance'') is able to do the 
typesetting.  It constructs the sum line, typesets the numbers,
calculates the totals, and checks whether the two columns are in
balance; if not, the user is warned via a message. A special command
\resetsumline exists which alllows one to restart a table, so that
multiple tables in one tabular environment are possible.
