% \section{Introduction}\label{intro}
-% The package |fcolumn| provides the macros for an extra tabular specifier that makes creating
-% financial tables easy. 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 group separator, |#2| is the decimal mark, and |#3| the coding used for
-% grouping digits of the integer part and decimal part.
+% The package |fcolumn| provides the macros for an extra tabular specifier
+% that makes creating financial tables easy. 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)~grouping
+% character of the integer part on output, 2)~decimal mark used on output,
+% and 3)~compact additional information on input/output characteristics,
+% see below.
%
-% The f-column in the current version of the package is defined for the continental European
-% standard: |\newcolumntype{f}{F{.}{,}{3,2}}|. This means that a number like 1234567 will be
-% typeset as $12{.}345{,}67$. People in the Anglo-saxon world would rather
-% code |\newcolumntype{f}{F{,}{.}{3,2}}|, yielding $12{,}345{.}67$ for the number given above.
-% The default value for |#3| is 3,2, indicating that grouping of the integer part
-% is by three digits and that the decimal part consists of two digits.

+% People in the Anglo-saxon world would rather code
+% |\newcolumntype{f}{F{,}{.}{3,2}}| for the same input, yielding
+% $12{,}345{.}67$ as output for the number given above. The default
+% value for |#3| is |3,2|, indicating
+% that grouping of the integer part is by three digits, that a comma is
+% used in the \TeX-source to indicate the decimal separator, and that
+% the decimal part consists of two digits.
% If however, in your country or company grouping is done with a thinspace every
-% four digits and there are three digits after the decimal mark---that happens to
-% be a |\cdot|---, then simply specify |\newcolumntype{f}{F{\,}{\cdot}{4,3}}| in
-% that case.

+% and there are three digits after the decimal mark---that happens to be a

+% that case. The input could be 12345p678 then, yielding $1{\,}2345{\cdot}678$
+% as output.
%
% By default two digits are used for the decimal part, so if you really
-% want no decimal digits (in that case of course also skipping the decimal mark)

% \section{Commands}
% The user only needs to know six commands or constructions. These six are given here.
% \begin{macro}{F}

-% version |f|, where the three arguments of |F| are |{.}|, |{,}|, and |3,2|. If you
-% want |g| to be your own definition like the curious one given in Section~\ref{intro}, then

-% explicitly escaped by |\leeg|, see below. The numbers are typeset according to the template
-% the user gives with his/her |F|-column.

+% explicitly escaped by |\leeg|, see below. The numbers are typeset
+% according to the template the user gives with his/her |F|-column.
+% The ``middle'' character of |#3| is an important switch: it does more
+% than just setting the input decimal mark. By default the input grouping
+% character is the dot, except when the dot is specified as input decimal
+% mark; in that case the comma is acting as input grouping character. With
+% this convention the continental Europe and Anglo-saxon part of the world
+% is served.
% \end{macro}
% \begin{macro}{\sumline}
-% The numbers in an |F|-column are typeset as a financial amount, but the real benefit comes
-% with the |\sumline|. It does three things:
-% \begin{compactitem}
-% \item It calculates the total of the column so far and the maximum width encountered

+% \begin{compactenum}[1)]
+% \item It calculates the total of the column so far and the maximum width
+% encountered so far, including the width of the total;
% \item It generates a rule with width calculated in the first item;
-% \item It checks the columns that are supposed to balance whether or not they actually do.
-% If so, nothing happens. If not, a |\message| is given that column $i$ and $j$ do not balance,
-% where $i$ and $j$ are the relevant columns. This is only done if the total number of
-% |F|-columns is even, e.g., if there are six |F|-columns, then~1 is checked against~4, 2 against~5,
-% and 3 against~6. If the number of |F|-columns is odd then anything could be possible in that table
-% and nothing is assumed about structure within the table. This behaviour can be overridden, see below.

+% \begin{macro}{\leeg}
+% This macro is used to overrule the default behaviour of the pair |\b@fi|
+% and |\e@fi|. It starts with ending the groups in the
+% same way that |\e@fi| would normally do. Then the effect of |\e@fi|
+% (that is still in the preamble) is annihilated by |\let|ting it to
+% be |\relax|. This |\let| is only local to the current column. Then
+% the argument to |\leeg| is treated in a similar way as |\e@fi| would
+% do with a typeset number.

-% The output is only to screen and the transcript file; it doesn't change the appearance of your

-% \meta{count}s from previous calculations has become irrelevant at this moment.

+% at-sign. By defining |\leeg| in this way, instead of |\multicolumn1r{}|
+% (which contains |\omit|), the default spacing in the column is retained.
