CurrencyString shows ?

FormatCurr('%M',111111111) -> %M

Expected a currency string as '111.111.111,00 ?'

System: Linux, Debian Sid

sorry for that really idiotic question :-))

Why do you think %M is a formatting character ?

Valid formatting characters are described at:

http://www.freepascal.org/docs-html/rtl/sysutils/formatfloat.html

Hi Michael,

sorry, i still don't get it:

Help to FormatFloat tells me:
"FormatFloat formats the floating-point value given by Value using the format specifications in Format."

.. and help to Format:
"M Currency Format ..."

So please correct my,
FormatCurr('%M',111111111)
so i am able to understand my mistakes ...

thank you!

Ok, i'm stupid!!!

This is how it works with the %m format

procedure TForm1.FormCreate(Sender: TObject);
begin
   DefaultFormatSettings.Currencystring := '?';
   Label1.Caption := Format('%m', [11111111.0]);
   // "Format" instead of "FormatCurr", parameter in square brackets,
value must be a float
end;

As Michael said "%M" is not a format specifier for the FormatCurr function, use "0.00" to get two decimal places . Moreover, as I see in my tests, the currency symbol is not added (because "FormatCurr()" internally calls "FormatFloat()"). I must confess that the docs are quite confusing here...

This should work
   Label2.Caption := FormatCurr('0.00 ?', 111111111.0);

To add to that, CurrencyFormat() shows in the docs as "deprecated", but it doesn't suggest a function that replaces it.

"FormatCurr formats the currency Value according to the formatting rule in Format, and returns the resulting string."

here <Format> refers to the parameter format, not the function, as you seemed to surmise.

Yet the next sentence in Help
"For an explanation of the formatting characters, see FormatFloat. "

Should have given you a clue.

Well, I have adapted the text so it is less ambiguous.

Werner has given you a example of what to code.

Michael.

And here is a LateX issue in the docs for Format()

Under the "M" currency format text it shows:

Currency format. the next argument in the var{Args} array

The LaTeX "var{...}" is shown literally, instead of converted to Italic text. @Michael: Must I file a bug report, or will you make a note about it?

It will in 3.0:

Already done.

Michael.

A) thank you guys!!!

B) Werner Pamler ...

Fazit: ... so its not possible to get the currency symbol ? using FormatCurr, that what i learned so far?!!

i was wrong interpreting the function name as delivering a formatted number plus(!!) the currency symbol!

Because there might be cases in which you don't want the currency symbol. And better to manually add something than to remove something ;)
