[fpc-pascal] Currency symbol wrong location
Hi, I want to format a float number to currency. To do this, I use the Format
function using the %m format, as this:
Format('%m', [123.25]);
I'm using Ubuntu 12.04 and my regional settings at configured to display "$
1234.25", but I'm getting "123.25$", why is the money symbol at the right side,
instead of using the regional setting?.

[fpc-pascal] [Patch] there is a small bug in fcl-image imterpolation
in packages/fcl-image/src/fpinterpolation.inc when it calculates the interpolated color it must initialize the value of the variable NewCol with a quadruple of all zero but it actually uses colBlack which has RGB set to zero but alpha is $. This is wrong. It makes it impossible to scale any image with alpha channel (the colors are fine but the alpha channel will be messed up completely. This patch fixes it: Index: packages/fcl-image/src/fpinterpolation.inc === --- packages/fcl-image/src/fpinterpolation.inc (Revision 21487) +++ packages/fcl-image/src/fpinterpolation.inc (Arbeitskopie) @@ -179,7 +179,7 @@ begin sx:=PInteger(xEntry)^; inc(xEntry,SizeOf(integer)); - NewCol:=colBlack; + NewCol:= colTransparent; for cx:=0 to xSupport-1 do begin f:=PSingle(xEntry)^; @@ -198,7 +198,7 @@ for dx:=0 to w-1 do begin CurEntry:=yEntry+SizeOf(integer); -NewCol:=colBlack; +NewCol:=colTransparent; for sy:=0 to ySupport-1 do begin f:=PSingle(CurEntry)^; Instead of starting with colBlack which is (0,0,0,$) it must start with colTransparent which is (0,0,0,0) After applying this patch I can now properly scale images with alpha channel.

Did you use the CLocale unit ?

No, but after you mentioned I included it in my "uses". The result was a number
without the money symbol.

Apart from that, I'm looking a cross-platform solution.

That probably means the clocale does not know how to handle the currency symbol
?

This is as per doc?
http://www.freepascal.org/docs-html/rtl/sysutils/format.html
FloatToStrF(Argument,ffGeneral,Precision,3)
MCurrency format. the next argument in the var{Args} array must be a
floating point value. The argument is converted to a decimal string using
currency notation. This means that fixed-point notation is used, but that
the currency symbol is appended. If precision is specified, then then it
overrides the CurrencyDecimals global variable used in the FloatToStrF
In short, the M specifier formats it's argument as follows:
FloatToStrF(Argument,ffCurrency,,Precision)
Note the /append/ :-)

Then there seems to be a contradiction in the doc. The position of the
currency symbol in FloatToStrF with ffCurrency is determined by
CurrencyFormat.
CurrencyFormat:=0;
s:=FloatToStrF(123.25,ffCurrency,5,2);
s:=Format('%m', [123.25]);
Both calls return $123.25 in s.

Thanks, that worked. The trick was CurrencyFormat := 0;
