Format a whole column using ";%.2f" in orgtbl?

Format a whole column using ";%.2f" in orgtbl?

[AW]

Hi,

I'm using radiotables and would like to get all numbers of column 1 with two 
digits after the decimal separator. My example below leads to an error, but it 
may explain what I'd like to receive:

Input:

| 100 | Value |
| 150 | Value |
#+TBLFM: $1=%s;%.2f

Desired outoput:

| 100.00 | Value |
| 150.00 | Value |
#+TBLFM: $1=%s;%.2f

I also tried to use :fmt (1 %s;%.2f)
while exporting to LaTeX, but in vain. 

Regards,
Alexander

What you tried would be

| 100.00 | Value |
| 150.00 | Value |
#+TBLFM: $1=$0;%.2f

$0 is the current table field. What I recommend is

| 100.00 | Value |
| 150.00 | Value |
#+TBLFM: $1 = $0 +.0; f-2

because of the behavior I explained in the tables shown here:

O.K., thank you very much for your help. This is a nice trick!

Unfortunately, my tables have other formulas than only one:

| Values | Desc. |
|--------+-------|
| 100.00 | Value |
| 150.00 | Value |
|   250. | sum   |
|--------+-------|
|   500. | End   |
#+TBLFM: @4$1=@2$1+@3$1::@5$1=vsum(@I..@II)::$1=$0 +.0; f-2

I get at least every number in column 1 with a dot, but without ".00", as 
needed: 

*Do I have to ad '; f-2' to every formula?* 

And besides that, I've never seen this description "f-2". Is it explained 
somewhere for non-mathematicians? You know, if there are differences between 
this and ";%.2f", I should better be aware of them. 

Regards

Alexander

The ending dot is Calc syntax and means a float with fraction 0.

Yes, else the Calc result is inserted without change. There is a
formula debugger that shows the formatting steps nicely: "C-c {"

The "+.0" is necessary too to convert Calc integer to Calc float for
some cases as shown in the example tables here:
http://orgmode.org/worg/org-faq.html#table-float-fraction

All together:
#+TBLFM: @4$1=@2$1+@3$1 +.0; f-2::@5$1=vsum(@I..@II) +.0; f-2::$1=$0 +.0; f-2

This is what I recommend just in general and what I do always myself
as a habit because it can deal also with higher precision or the case
when those of the fields resulting in an empty string should remain
empty instead of a "0.00". If you don't want to be prepared for all
that, for your current example you can still use just

#+TBLFM: @4$1=@2$1+@3$1;%.2f::@5$1=vsum(@I..@II);%.2f::$1=$0;%.2f

For an explanation see the URLs to the Calc manual mentioned here
http://orgmode.org/worg/org-faq.html#table-float-fraction
after "For f3 and f-3 see `d f' (`calc-fix-notation')".
